Ramses Composer - Change Log

[1.10.0] Multiedit, Shader Includes, Drag-and-drop Support, Misc Usability Improvements and Bugfixes

Added

  • Added support for the multiple edit functionality in the property browser.
  • Added support for #include directives in shader files. Include directives can be nested. The path of the included files must be relative and will be interpreted relative to the path of the shader file containing the include.
  • Added support for opening .rca files using drag-and-drop.
  • Added drag-and-drop support for resource files (.gltf, .glb, .ctm, .png, .vert, .frag, .geom, .def, .glsl). Dropping a resource file on a URI property will fill the property. Dropping a resource file in the treeviews will create a new resource object.
  • Added application preference to optionally enable the case-sensitive URI validation. The default is off.
  • Added functionality to save screenshots of the preview using the GUI application and exposed via the Python API.
  • Added resolveUriPropertyToAbsolutePath function to the Python API to obtain the absolute path from a uri property.
  • Added a feature level update python script and updated the python migration scripts in the python subdirectory.
    • Use the migrate_recursive_v1.0.1.py script to update projects from RaCo version <=1.0.1 to the current version. Keeps feature level.
    • Use the migrate_recursive.py script to update projects from RaCo version >=1.1.0 to the current version. Keeps feature level.
    • Use the upgrade_fl_recursive.py script to perform a feature level upgrade to a specified feature level. Also updates the projects to the current RaCo version.
    • All scripts will update the main project and all external projects used by it.
    • Detailed usage information is contained in the scripts and can be obtained by running the script with the Python interpreter directly.
  • Added section on feature levels to the Basics/Introduction chapter of the documentation.

Changes

  • Top-level objects in the scenegraph are now moveable.
  • The folding state of non-locked property browsers is preserved and saved in a cache per session for all expandable properties.
  • Added a new confirmation dialog to prevent accidental file version upgrade on Save. The appearance of this dialog is controlled via a new option in the preferences dialog.
  • Adjust the behaviour of the -f commandline option in the GUI application to ensure that projects specified on the commandline will load regardless of the feature level set in the preferences dialog. The behaviour is now as follows:
    • default feature level for new projects
      • set via the preferences dialog in the GUI application
      • set via the -f commdandline option in the headless application
    • initial project load feature level
      • set via the -f commdandline option in both gui and headless applications.
      • if specified the initial project given using the -p option will be upgraded to the given feature level.
      • if no initial project is specified the initial default project will be created with the given feature level.
      • if no -f option is used the initial project given the -p option will be loaded at the feature level of the project itself.

Fixes

  • Don't optimize away LuaInterfaces with invalid links ending on them when exporting a scene. Note that invalid links ending on non-existing properties will not have associated error items indicating an invalid link.

[1.9.1] Bugfix Release

Fixes

  • Prevent stencil and scissor options in materials and meshnodes from being reset to their defaults by undo/redo operations.

[1.9.0] Stencil & Scissor support, Linkable instance count, Texture optimization, Misc Bugfixes

  • File version number has changed. Files saved with RaCo 1.9.0 cannot be opened by previous versions.

Known Issues

  • Setting a MeshNode instanceCount property to a negative value via a link will lead to a runtime crash in Ramses.

Added

  • Added support for stencil testing via new stencil-related properties in the Material and MeshNode options.
  • Added support for scissor testing via new properties in the options container of the Material and MeshNode types.
  • Added color write mask suport in the Material and MeshNode options.

Changes

  • Added support for direct list/tuple assignment to properties of vector type in Python API.
  • Available at feature level 5: made the instanceCount property of MeshNodes linkable.
  • Optimize the texture format in Ramses for normal Texture objects. No duplicate color channels or channels with constant values are created anymore. This removes warnings about creating empty channels.
  • Do not display warnings for unlinked interfaces in Export dialog

Fixes

  • Don't allow to create links between Vec2f/etc properties and struct properties with the same child properties since they can't be created in the LogicEngine.
  • Fixed the potential loss of struct uniform values in MeshNodes when loading a file created with RamsesComposer V1.7.0 or earlier with V1.8.0.
  • Fix preview scaling to make the scale equal to the device pixel over scene size ratio where the scene size is given by the Display Size property in the ProjectSettings object.

[1.8.0] Free Tagging System, Lua Logging, Linkable Struct Uniforms, Misc Bugfixes

  • File version number has changed. Files saved with RaCo 1.8.0 cannot be opened by previous versions.

Added

  • Introduced free tagging system by adding a userTags property to all object types.
    • The user tags are independent of the normal tags property controlling the render setup.
    • They can be accessed in the Python API using the new getUserTags/setUserTags functions analogous to the normal setTags/getTags functions.
    • Added filtering by user tags to the tree views.
  • A facility generating custom log messages from LuaScripts, LuaInterfaces, and LuaScriptModules using the rl_logInfo, rl_logWarn, and rl_logError functions has been added.
    • Calling these functions will result in a log message being generated by the LogicEngine with the string argument of the function as message.
    • The logging facility is enabled in normal operation in RamsesComposer but will be disabled during export. This may lead to export failing if the logging functions are called.
  • Added full support for linkable struct uniforms. Instead of a flattened property structure for struct and array of struct uniforms the application now builds the same recursive property structure as for LuaScripts. This makes uniforms structs linkable as a whole.
  • Added support for the lua saving mode in the export dialog and the Python API. The lua saving mode can be also specified using the '-s' command line option in the headless application.

Fixes

  • "Save As with new ID" will now change all object IDs in the saved project. It is therefore possible to use objects from both the original and the copy as external references in the same project. The save function of the Python API had to remove the 'setNewID' flag and doesn't support "Save As with new ID" anymore.
  • Fixed missing link validity update for links starting at external objects and ending on local objects when the set of properties of the starting object has changed in the external project.
  • Fixed category names for BlitPass and RenderBufferMS types in the resource view.
  • Fixed crash when moving multiple interlinked objects out of a Prefab.
  • Fixed Ctrl+C shortcut to consistently copy the selection from the Python Runner and the Property Browser. Removed Copy and Paste commands from Main Menu, because they are now pane-specific.

[1.7.0] External Textures

  • File version number has changed. Files saved with RaCo 1.7.0 cannot be opened by previous versions.

Added

  • Added new TextureExternal type and support for the corresponding samplerExternalOES uniform type.
    • To use samplerExternalOES uniforms the shader needs to enable the extension for it with #extension GL_OES_EGL_image_external_essl3 : require.
    • This can be used to create textures which may be connected at runtime to external buffers also created at runtime. Since no external buffers can be set up in RamsesComposer these will be rendered in black in the preview.

Changes

  • Update ramses-logic from 1.4.1 to 1.4.2.
  • Update ramses from 27.0.128 to 27.0.130.

[1.6.0] Skinning, Morphing, property copy/paste, modules for Lua interfaces, misc bugfixes

  • File version number has changed. Files saved with RaCo 1.6.0 cannot be opened by previous versions.
  • Export now supports ramses-logic feature levels up to 5. Scenes exported with feature level 4 can't be opened with ramses-logic before v1.3.0. Scenes exported with feature level 5 can't be opened with ramses-logic before v1.4.1.
  • Starting at feature level 5 modules() statements in LuaInterfaces are not silently ignored anymore. Upgrading a scene to feature level 5 may therefore result in errors appearing in the scene which can be remedied by removing the offending modules() statements or supplying a module as needed.

Known Issues

  • Animations of rotations are currently only working correctly for single-axis rotations due to an issue in the LogicEngine.

Added

  • Added support for vertex skinning and import of skinned meshes from glTF files.
  • Added basic support for morphing: morph target position and normal mesh vertex attributes and morph weight animations will now be imported from glTF files.
  • Added Copy/Paste functionality to all properties, accessible through their right-click context menu.
  • Available at feature level 5: Added support for lua modules used in lua interfaces.
  • Added indicator for nodes visibility to SceneGraph and Prefabs view.
  • Added release_headless build folder with Ramses Composer Headless. It can be shipped and run independently from Ramses Composer Editor.
  • Added "MSAA off" option to Ramses preview window and remove "MSAA 1x" option. The MSAA off option uses nearest neighbor filtering.

Changes

  • Update ramses-logic from 1.3.0 to 1.4.1.
  • Update ramses from 27.0.126 to 27.0.128.

Fixes

  • Fixed crash in GLTF import dialog when importing with some items deselected and then trying to import again from the same file.
  • Fixed crash on startup in case oldest log file is locked by a running process.
  • Restrict feature level to the maximum supported one in the GUI application on startup to avoid crash when the feature level in the ini file is too high.
  • Made error message in RenderTarget with mixed multi-sampled and normal buffers more descriptive.
  • Prevent Recent Files menu from force downloading OneDrive files.
  • Consistently show "Export with errors" in export dialog when RaCoHeadless would not export the scene.
  • Fixed broken coloring in Python runner log.
  • Consistently use relative paths in the created resource uris when importing from glTF files.
  • Fix file not found errors when encountering files with links in their paths. This removes the URI case-sensitivity on Windows systems.
  • Fix TracePlayer unintended retention of Lua properties values between trace loads.
  • The glTF mesh import has been fixed to correctly transform and normalize the normal vectors when baking all meshes in the glTF file into a single mesh object.

[1.5.1] Bugfix release

Changes

  • Import dialog items are split into Scene Graph and Resources categories.

Fixes

  • Control of render order by manually changing a renderableTags child property of a RenderLayer now works correctly.
  • Make error color in Python runner readable.
  • Ignore RenderBufferMS-related errors when exporting as a workaround for a Ramses bug.

[1.5.0] Multisampling, dynamic render order control, Python API improvements

  • File version number has changed. Files saved with RaCo 1.5.0 cannot be opened by previous versions.
  • Export now supports ramses-logic feature levels up to 3. Scenes exported with feature level 3 can't be opened with ramses-logic before v1.2.0.

Added

  • Available at feature level 3: Dynamic control of render order by making the individual renderableTags properties for each tag linkable.
  • Python API changes
    • Added get/setTags, get/setMaterialFilterTags, and get/setRenderableTags functions to access the tags, materialFilterTags, and renderableTags properties en bloc.
    • The renderableTags property in RenderLayer objects is now visible from Python to allow linking it.
    • Added addExternalProject(path) to add a project as external reference.
    • Added addExternalReferences(path, type) to import all objects of a certain type as external references. Type can be either a single string or a list of strings to import multiple types at once. Returns the imported objects.
  • Multisampling support
    • Added MSAA option to Ramses preview window.
    • Added RenderBufferMS usertype that handles Ramses TextureSampler2DMS objects.
    • Added Material support for shader uniform type sampler2DMS.
    • Added new example shaders multisampler.(frag/vert).
  • Added BlitPass usertype.
  • Added support for array uniforms in shaders. Only simple types but not struct are supported as array elements.

Changes

  • Update ramses-logic from 1.1.0 to 1.3.0.
  • Update ramses from 27.0.121 to 27.0.126.
  • Items in the Resource View are now grouped by their type.
  • If exporting in headless fails, the errors causing that failure are now always logged into the console output.
  • Upgrade Feature Level menu moved down below Save As...
  • TracePlayer now throws an error together with the trace line number, timestamp and the step at which error occurs.
  • "Save As with new ID" added.

Fixes

  • Removed double scrollbar in Project Settings.
  • Fixed wrong Feature Level number in RCA file after upgrade.
  • Fixed misleading error message sometimes appearing for empty texture uniforms.

[1.4.0] Python API enhancements, various usability improvements and bugfixes

Added

  • Added better support for feature levels in the GUI application
    • Default feature level for new projects can now be set via the preferences dialog.
    • Added "File/Upgrade Feature Level" submenu to upgrade the currently active project to a higher feature level. This will first save the project. Afterwards it will load the project again while upgrading to the desired feature level.
    • Loading a project which uses an external project with a higher feature level will show a dialog allowing the user to upgrade the feature level of the loaded project to the feature level of the external project.
  • Added mesh metadata display for unbaked Meshes, e.g. gltf-extras values (currently string values only)
  • Python API improvements
    • Added feature level parameters to functions reset and load.
    • Added keys() member function to objects and properties.
    • Added property access via indexing operator [] for objects and properties.
    • Added hasSubstructure() member function for properties.
    • Added more checking of error conditions.
    • Added getInstanceById(id) function to get a specific instance.
    • Added isRunningInUi() function to query if RaCo is running in gui application.
    • Added minFeatureLevel() and maxFeatureLevel() functions to determine currently supported feature levels.
    • Added isReadOnly(), isExternalReference() and isResource() member functions to objects.
    • Added getPrefab(), getPrefabInstance() and getOuterContainingPrefabInstance() member functions to objects. These return either None or the respective prefab/prefabInstance.
    • Added isReadOnly(), isValidLinkStart() and isValidLinkEnd() member functions for properties.
    • Added getErrors() function to read active errors as a list of ErrorItem.
    • Added metadata() member function to get any mesh metadata for a mesh object.
    • Added raco_gui python module, which is only available when running the composer in the GUI and needs to be imported separately.
    • Added getCurrentSelection() function to the raco_gui module, returning a list of the currently selected editor objects.
    • Added importGLTF(path, parent) to import a whole glTF file into the scene. path can be either relative to <projectFolder>/meshes/ or absolute, parent argument is optional. If not provided, the object will be attached to the scene root.
    • Added -y command line option for both headless and GUI application to set additional python module search paths. Multiple -y options may be specified to add multiple directories. The additional paths are added before the default search path.

Changes

  • Made URIs case-sensitive on Windows systems.
  • Made Export Dialogue less confusing
    • Removed Export Path Field.
    • Added buttons to select export target files.
    • Export Paths now use relative paths to increase readability.
    • Split the export summary to make it easier to differentiate between Scene Graph items and Resources.

    • Their visibility can now be toggled on and off.
    • Added a context menu option to directly open the referenced project.
  • Changed Python runner in UI from a dialog to a dock with added output functionality.
  • Error messages regarding external references now contain more information.
  • Object Name tooltips now display the name an object will have after export.
  • When importing resources, Git LFS Placeholder files are now detected and yield a helpful error message.
  • Retain tree view item name during an in-place edit until user changes it.

Fixes

  • Fixed Lua Runtime errors not being displayed within Error View in nested prefabs.
  • Realigned LuaInterface color picker/property expansion behavior with LuaScript behavior.
  • Fixed Linux linker errors when compiling with a higher gcc version than 7.5 (i.e. gcc-9 in Ubuntu 20.04 or gcc-11 in Ubuntu 22.04).
  • Fixed wrong glTF scenegraph getting shown when trying to import scenegraphs from .gltf files that have not been yet used in the project.
  • Changed naming of logfiles: create logfile names based on process id and remove the oldest ones based on modification time.
  • Added error item for inconsistent blend option settings in Material and private material of Meshnodes.
  • Optimize link removal to speed up saving of large projects.
  • Fixed a crash when pasting text from the clipboard without having anything selected.
  • Fixed preview "best fit" scaling to avoid showing scrollbar for all scene and preview dock size combinations.
  • The origin of the displayed coordinates when mousing over the preview dock is now in the lower left.

[1.3.0] Ramses Logic feature level 2 support, relinking, search function, UI improvements

  • File version number has changed. Files saved with RaCo 1.3.0 cannot be opened by previous versions.
  • Export now supports ramses-logic feature levels 1 and 2. Scenes exported with feature level 2 can't be opened with ramses-logic before v1.1.0 or with ramses-logic using feature level 1.

Added

  • Added support for LogicEngine feature levels
    • The current feature level of a project can be seen in the ProjectSettings object.
    • An application feature level can be set using the '-f' command line option in both the GUI and the headless application.
    • Creating a new project will use the application feature level. If the application feature level is set to -1 the maximum supported feature level is used.
    • Loading a project will set the current feature level to the project feature level if the application feature level is set to -1. If the application feature level is >=1 the project will be upgraded to the application feature level on load. Downgrading to a lower feature level is not possible.
    • Loading a project will always upgrade all externally referenced project to the feature level of the loaded project.
  • Added support for the following features available at LogicEngine feature level 2
    • Added new linkable enabled property to Nodes.
    • Allow using planes for the frustum of perspective cameras. Switching is performed using a new frustumType property in the PerspectiveCamera. The properties in the frustum container of the camera will be changed accordingly.
    • RenderPass property changes
      • Added a new linkable renderOnce property.
      • Renamed order to renderOrder to match the LogicEngine property name.
      • Made the enabled, renderOrder, and clearColor properties linkable.
    • Added the AnchorPoint user type.
      • Anchor points are LogicEngine objects calculating the viewport coordinates and the depth of a node origin as seen by a camera.
      • Anchor point objects can't be used as external references.
      • See LogicEngine documentation for details.
  • Added improved reference editor. The new reference editor follows the same functionality as the link start point editor.
    • Copied objects that are able to be used as references can be set as such a reference by right-clicking on the reference text box in the Property Editor.
  • Added tree view object filter ability.
    • Search words can be separated by space to combine multiple searches.
  • Added in-place renaming option for tree views.
  • Automatically fill the shader paths when the first path is set following a simple naming convention based on file extensions. Two naming conventions are supported
    • Extensions *.vert, *.geom, *.frag, *.def
    • Extensions *.vert.glsl, *.geom.glsl, *.frag.glsl, *.def

Changes

  • Allow relinking of external projects during load when a project file is missing.
    • A warning message is shown and the user can choose to supply a new project file to load instead of the missing project.
    • Only the loading process if affected, neither the main nor any external project are saved automatically.
    • Due to the removal of redundant information during file save the new project path will only be saved if the external project is directly used by the current project.

Fixes

  • Fixed the ~11 seconds freezing in RaCo Editor, under Linux with Nvidia in performance mode, when the Preview dock is resized.
  • Fix trace player to update the outputs of LuaScript objects correctly when locking objects.

[1.2.0] Trace player, weak links, and running Python script in GUI application

  • File version number has changed. Files saved with RaCo 1.1.2 cannot be opened by previous versions.

Added

  • Added ability to run Python scripts in the UI version.
    • Use the new command line argument "-r" to run Python scripts before the UI appears.
    • During UI usage, you can run Python scripts using the new dialog "File" -> "Run Script..."
      • Note that Python functions "load()" and "reset()" have been temporarily disabled for this particular use case as they are currently incompatible with scene switches in the UI.
  • Added TracePlayer
    • TracePlayer is used for simulation and debugging purposes, where a recorded, or manually defined, animation scenario in a RaCo trace file (.rctrace) can be loaded and played in the scene.
    • rctrace files are JSON based files that should contain so called frames of scene properties data in consecutive timestamps snapshots.
    • TracePlayer parses frames periodically based on RaCo application update time and updates the corresponding LuaScript or LuaInterface object(s) in the scene.
    • For more details with an example, see the TracePlayer section in the Ramses Composer documentation.
  • Added support for weak links. Weak links are ignored in the LogicEngine Lua dependency graph which determines the Lua execution order.
    • Weak links can be created in the UI when a loop would be created with a strong link.
    • Strong/weak links are indicated in the property browser by double/single left arrows next to the link menu button.
    • The Python API addLink received an additional argument to allow creating weak links.
  • Added "all file" filter for file dialogs that load files (e.g. URIs).

Changes

  • Changed "ramses-framework-arguments" ("-r") command line argument to "framework-arguments" ("-a").
  • Icons in read-only state (e.g. link icons of properties in the Property Browser) will retain their color now.
  • Removed lua script time_ms hack.

Fixes

  • Fixed incorrect update of PrefabInstance contents when loading a scene with a camera inside a PrefabInstance referenced by a RenderPass.

[1.1.2] Lua Interface Naming Bugfix

Fixes

  • Change names of LuaInterface objects in the LogicEngine to match the conventions used for LuaScripts. In particular
    • LuaInterface objects outside any PrefabInstance use the LuaInterface name in the LogicEngine.
    • LuaInterfaces which are direct children of a non-nested PrefabInstance are named <PrefabInstance name>.<LuaInterface name>
    • All other LuaInterfaces have the object ID of the LuaInterface object appended <LuaInterface name>-<LuaInterface object ID>.

[1.1.1] Lua Interface, Timer, and Animation Bugfixes

Fixes

  • Fixed migrate_recursive.py python script to avoid early exit in projects whose external projects graph has multiple paths to some external project.
  • Fixed warning about unlinked LuaInterface outputs when exporting by optimizing away LuaInterface objects in the LogicEngine which are unnecessary.
  • Fixed crash when attempting to create a link between an empty LuaInterface and an empty LuaScript, both with empty uri.
  • Prevent creation of link loops after removing link when multiple links between the same objects are present.
  • Fixed links starting on Animation output properties not working in LogicEngine.
  • Renamed Animation "animationOutputs" property to "outputs" for consistency with LuaScript and Timer property naming.
  • Fixed Timer objects being deleted all the time by "Delete Unused Resources" despite potential links to and from the Timer.

[1.1.0] Lua Interfaces, various UI improvements

  • File version number has changed. Files saved with RaCo 1.1.0 cannot be opened by previous versions.
  • Check the suggested migration procedure below for the LuaInterfaces introduced in RamsesComposer 1.1.0 to avoid unnecessary issues.

Added

  • Added LuaInterface objects
    • LuaInterfaces are created from an interface script similar to the Lua scripts but only containing an interface function and only defining input but not output properties. Interfaces can't use modules either. See the LogicEngine documentation for further details.
    • The input properties of LuaInterfaces can be both starting end ending points of links.
    • Interfaces do not have a run function and no Lua code is evaluated each frame.
    • LuaInterfaces replace the LuaScripts as interfaces for Prefabs. LuaScripts inside PrefabInstances are now completely readonly, i.e. their input property can't be changed or have links ending on them anymore.
    • Migration of Prefab/PrefabInstance interface LuaScripts to LuaInterfaces is performed automatically when loading an old project: new LuaInterface objects are generated for each interface LuaScript and the interface scripts files are generated in an interfaces/ subdirectory of the project directory. Furthermore the links ending on the interface LuaScripts are rerouted through the newly created LuaInterfaces leading to the same behaviour as before.
    • LuaInterfaces are also allowed outside Prefabs/PrefabInstances.
    • WARNING The migration code will generate and write the interface scripts each time it is run. If a file is loaded repeatedly without saving it the interface files will be overwritten each time. To avoid running the migration code repeatedly make sure to save the scenes after loading. A python migration script included in the release automates this process, see below.
  • Suggested migration procedure
    • Open main scene, make sure there are no errors, in particular no errors relating to scripts (including missing modules). Make sure all scenes have been migrated to RaCo 1.0.x.
      • If you do not ensure that the scripts have no errors, the LuaInterface objects generated for the scripts will not work as expected!
    • Use the Python migration script on the main scene, e. g. `\bin\RelWithDebInfo\RaCoHeadless.exe -r \python\migrate_recursive.py -l 3 -p .rca
      • Make sure to include the "-l 3" otherwise the console will be full with irrelevant info/debug/trace messages.
      • The script will perform the migration by loading and saving the main scene and all external scenes used by it.
      • The automatic migration might fail if multiple main scenes in the same directory are migrated like this since there might be conflicting versions of the new interface files being generated and written to the same file. This should not happen if there is only a single project file per directory.
    • Open the scene in RaCo again and verify the scene.
    • The generated interface files are now safe to be edited and will not be overwritten on subsequent loads of the project.
    • Make sure the C++ coders loading and using the scene change their code to search for LuaInterface objects instead of LuaScript objects, if the object they try to find is part of a prefab instance.
    • (optional optimization) Strip all simple OUT=IN assignments from the scripts serving as prefab interfaces and link those properties directly to the LuaInterface objects. This can decrease the CPU load of your scene on the target significantly due to the link optimization (see below).
  • Added link optimization when exporting: links chains that have only LuaInterfaces in the middle of the chain will be replaced by single link from the chain start to the chain end property.
  • Added Ramses log output to RaCo log output.
    • Ramses trace-level log output has to be explicitly activated in the RaCo Editor with the command argument "-t".
  • Added custom Texture mipmap support, similar to CubeMap's mipmap support.
  • Added tooltips for RaCo properties showing the RaCo-internal property name.
  • Added more information to Texture and CubeMap information boxes.
  • Allow configuration of standard modules used for lua scripts and modules via a new stdModules property in LuaScript and LuaScriptModule types.
  • Added context menu item in the Treeview and Project Browser to open the external project(s) of the selected objects in a separate RamsesComposer instance.
  • Added keybord shortcuts for the toolbar menus of the main window.
  • Added "u_Resolution" as builtin shader uniform in addition to "u_resolution".

Changes

  • Update from ramses-logic 1.0.2 to 1.1.0
  • Update from ramses 27.0.119 to 27.0.121
  • Disallowed referencing objects inside Prefabs from objects outside of the same Prefab.
  • Disallowed moving top-level objects onto top-level places inside the same objects tree view.
  • Extended Texture & Cubemap information to show color channel flow from origin file to shader channels.
  • Texture format down-conversion message has been downgraded from warning to information level.
  • Texture format up-conversion warning message has been declared as deprecated as it will be upgraded to an error soon.
  • Texture format conversion message from palette to any 8-bit format has been downgraded from warning to information level.
  • Add python script path as first element of sys.argv during script execution with RaCoHeadless.
  • Renamed some Node/MeshNode/PerspectiveCamera/OrthographicCamera/PrefabInstance, Timer and LuaScript/LuaInterface properties so they are closer to their ramses-logic counterparts.
    • Attention: This affects Python scripts that directly accesses properties by name.
  • Added projectPath function to Python API to query the path of the current project.

Fixes

  • Fixed crash when switching scenes after an Export Dialog that shows scene errors has been closed.
  • Fixed repeated Ramses DisplayDispatcher "no renderer events" message appearing in log.
  • Fixed texture not being loaded when using RG8 mode on grayscale pictures.
  • Raise python exception if Python API load is called with an empty string as filename argument.
  • Fixed crash when saving files with relative paths using Python API.
  • Add missing TextureFormat enum to Python API.
  • Fixed greyscale PNGs not looking correct when texture format RG8 is selected.
  • Fixed goto button not working when the referenced object is not selectable in the scene graphs of the current layout.
  • Fixed logging of error messages for projects loaded in the RaCoHeadless application to include errors generated by the Ramses/RamsesLogic engine interface code.
  • Fixed link removal in Python API to fail when attempting to remove links ending on read-only objects, e.g. external reference objects or PrefabInstance contents.
  • Removed spurious "discard invalid link" warning with empty start and/or endpoints when pasting as external reference.
  • Fixed crash when moving Nodes to root level in scenegraph.

[1.0.1] Fix export differences between RaCoHeadless and Ramses Composer GUI

Fixes

  • Ensure correct export in RaCoHeadless application by flushing the ramses scene before export.
  • Remove warning for "time_ms" Lua input parameter.

[1.0.0] ramses-logic 1.x, Python API, timer, new animations

  • File version number has changed. Files saved with RaCo 1.0.0 cannot be opened by previous versions.
    • rca files saved with this version will be much smaller than files saved with previous versions.
  • Export file format has changed. Scenes exported with RaCo 1.0.0 / ramses-logic 1.0.2 cannot be opened by ramses-logic versions 0.x.
  • Breaking Change: ramses-logic 1.0.2 uses a different lua syntax for the type definitions and the interface() and run() function definitions.
    • See the ramses-logic CHANGELOG.md for details.
    • A migration script provided by ramses-logic that converts the lua syntax is included as migrate_to_v1.0.py in the root folder of the RaCo package.
      • The migration script needs to be run twice - once for adding the IN,OUT parameter to the interface()/run() functions, and once to update the name of the types.
      • Example for running the migration script in your root project folder on Windows (adjust paths as required):
        • cd MyProjectFolder
        • python \RaCoInstallationFolder\migrate_to_v1.0.py inout .
        • python \RaCoInstallationFolder\migrate_to_v1.0.py types .
      • You might need to install the click Python module using pip install click to run the migration script.

Added

  • Added Python API and the ability to run python scripts using the RaCoHeadless application.
    • Added "-r" commandline option to RaCoHeadless application to run python scripts.
    • For a description of the Python API see the PythonAPI.md file.
  • Added new Resource type Timer as an interface to the ramses-logic timer.
  • Added support for more PNG image formats and Ramses texture formats.
    • Previously imported .pngs for Textures may need to be reconverted as the texture format detection has become more stringent.
    • Only supported PNG color types: R, RG, RGB, RGBA
      • Palette PNGs are loaded and converted for legacy reasons but will always cause a conversion warning.
    • 8-bit PNGs can only be used 8-bit for Ramses texture formats and vice versa with 16-bit PNGs.

Changes

  • Update from ramses-logic 0.15.0 to 1.0.2
  • Update from ramses 27.0.116 to 27.0.119
  • Nested arrays in LuaScripts are now supported. See the ramses-logic Changelog for details.
  • Ramses-logic objects created in RaCo scenes will share the same ramses-logic user ID as the respective RaCo object.
  • Animation objects have been simplified and now only have a 'progress' input property.
  • The Error View in the dock now also shows errors by external references, and is now consistent with the "Composer Errors" tab in the export dialog.
  • Redundant data has been removed from the rca file - if you are using many prefab instances or external references, expect your files to shrink significantly.

Fixes

  • Always perform a logic engine update when loading a file to avoid inconsistent states when exporting with the headless application.
  • Export with headless version will not write exported files anymore when the project can't be loaded.
  • The RaCoHeadless application will now return a non-zero exit code if loading a project fails, the export fails or a python script throws an exception.
  • Fixed RaCoHeadless crash when a scene extrefed by a loaded scene cannot be found.

Known Issues

  • It is currently not reliably possible to use venv/virtualenv with the RaCoHeadless Python API.

[0.14.0]

  • Export file format has changed. Scenes exported with RaCo 0.14.0 / ramses-logic 0.15.0 cannot be opened by previous ramses-logic versions.
  • Breaking change: Due to the update to ramses-logic 0.15.0 it is no longer possible to use variables without the "local" keyword or have global functions outside the "init" function. See the ramses-logic CHANGELOG.md for details.

Added

  • When dragging a property slider, you can now hold Shift to increase the magnitude of steps, and for float properties, you can also hold Alt to decrease the magnitude of steps.
  • Added goto button for link start/end properties.
  • Added tooltip for objects that are part of a PrefabInstance in the Reference drop-down selection.
  • Added tooltip for the link button & link editor that shows the full scenegraph path of link property root objects.

Changes

  • Update from ramses-logic 0.14.2 to 0.15.0
  • Update from ramses 27.0.115 to 27.0.116

  • The log view now displays a tooltip with the full multi-line message if the mouse is hovered over a message.
  • Sort all objects and links in the project file to ensure a stable order when saving repeatedly.
  • Change the displayed name of the member properties of the camera viewport and frustum containers to match the internal property name to make it easier to create matching struct definitions in lua.
  • Removed redundant information from the .rca files. External projects only indirectly used are removed from the external projects mapping in the saved file.

Fixes

  • Clicking the goto button of an Ext Ref object while having a Project Browser will now always lead to the actually referenced Ext Ref object instead of (sometimes) the object in the Project Browser.

[0.13.1]

  • **File version number has changed. Files saved with RaCo 0.13.1 cannot be opened by RaCo versions 0.12.x or earlier. **

Known Issues

  • RaCoHeadless will crash when trying to load a scene using external references from scenes which cannot be found.
    • The crash will be preceded by an error message like this "External reference update failed: Can't load external project '...' with path '....rca'"
    • If the same scene is opened in the Ramses Composer, the same error message will be displayed in a message box.
    • When this occurs, the best way forward is to restore the file in the stated location.

Fixes

  • Don't reset preview background color to black if the preview is resized or moved.

  • Collapsed vector view for floats does round the displayed number again.

  • Capturing the ramses-logic output revealed a ramses-logic error message during load caused by attempting to initialize scripts using modules which have not been loaded yet.

  • The "Export" button could be disabled without explanation if external references caused entries in the error view.

  • Material uniform textures which are unset now show an error message, since exporting them with ramses does not work.

  • Fix losing input properties of interface LuaScripts in nested PrefabInstances with externally referenced Prefabs during load. This fix breaks the propagation of the values of new LuaScript interface properties in the Prefab update performed as part of external reference update during load.

  • Fixed Ramses Composer not being able to launch under certain multiple display arrangements on Linux.

  • Fixed internal side-effect handling of LuaScript module property updates.

  • Under some circumstances RaCo attempted to delete Lua Modules in ramses-logic before the referencing Lua Scripts when the scene was closed, causing an error to be logged.

Changes

  • The "Export" button in the export dialog is no longer disabled if there are errors in the scene. Instead its label is changed to "Export (with errors)".
  • The error view in the export dialog now shows all errors, including the ones caused by external references.

[0.13.0] Compressed project files, cubemap extensions, log view

  • File version number has changed. Files saved with RaCo 0.13.0 cannot be opened by previous versions.
  • Version was superseded by 0.13.1 while still being a preliminary release.

Known Issues

  • RaCoHeadless will crash when trying to load a scene using external references from scenes which cannot be found.
    • The crash will be preceded by an error message like this "External reference update failed: Can't load external project '...' with path '....rca'"
    • If the same scene is opened in the Ramses Composer, the same error message will be displayed in a message box.
    • When this occurs, the best way forward is to restore the file in the stated location.

Added

  • Added custom CubeMap mipmap support.
  • Added optional automatic zipping of project files.
    • With automatic zipping enabled, projects will be saved as ZIP archives that still use the .rca file extension and contain the project JSON file.
    • This option can be enabled/disabled in the Project Settings (disabled by default).
  • Added command line argument "--outlogfile" to headless Ramses Composer for changing the log file path.
  • New log view allows observing Ramses Composer log output within the application.
  • The ramses logic datatype INT64 is now supported.
  • Added object duplication feature via context menu or shortcut.

Changes

  • Log file size is now limited to 10 MB, with new log files being created once this is exceeded. A maximum of 250 MB of log files can be created before old files get deleted.
  • Opening the link editor no longer has the search field pre-filled with the name of the current link, if one exists.
  • More details for LuaScriptModule errors in LuaScripts - invalid LuaScriptModule assignments are now also shown as individual errors.

Added

  • Added animation support.
    • Currently only animations defined in glTF files are able to be imported.
    • The first new user type AnimationChannel is a low-level data accessor for animation data, akin to the Mesh type.
    • The second new user type Animation is a scene graph object that groups AnimationChannels and contains the channels' linkable outputs.
    • Importing assets via the "Import glTF Assets" option will automatically create links from enabled Animations to the respective enabled Nodes.
  • Added quaternion rotation for Nodes.
    • Quaternion rotation is activated by linking a vec4f output to the Rotation property of a Node. The rotation property will then show the converted Euler angles as calculated by ramses-logic.

[0.9.2]

Changes

  • Update from ramses-logic 0.10.2 to ramses-logic 0.11.0
    • ramses-logic 0.11.0 introduces a new "init()" function for global variables. For details see ramses-logic CHANGELOG/docs.
  • Update from ramses 27.0.112 to ramses 27.0.113
  • Windows and Linux builds no longer contain debug symbols, reducing the size of the zip files significantly.
  • For now remove button "Check Resources Used by Enabled Nodes" from the "Import glTF Assets..." dialog to avoid confusion.
  • Reshuffling of library code:

Changes

  • File version number has changed. Files saved with RaCo 0.9.1 cannot be opened by previous versions.
  • Update from ramses-logic 0.9.1 to ramses-logic 0.10.2
    • This restores the behaviour of ramses-logic 0.7 (interface method can access things outside its scope). This is a temporary revert and will be reintroduced in an upcoming version again, along other hardening measures!
  • Update from ramses 27.0.111 to ramses 27.0.112
  • "Import glTF assets..." can no longer import into the root of the scene.
    • This is to avoid the need to tag the imported scene to make it visible.
    • The menu point has been removed from the "File" main menu as well as the context menu for the root.
    • It is now only displayed for object tree entries in which nodes can be created.
  • A renderable referenced by a render layer, but not by a render pass now shows the directly referencing render layers in its property browser.
  • Render layer property naming changes:
    • The "Sort order" property is now called "Render Order".
    • The options for the "Sort Order" property are now called "Render order value in 'Renderables Tags'" (default) and "Scene graph order".
    • The column header in the tag editor for 'Renderable Tags' specifying the render order is now called "Render Order".
    • The "Incl./Excl. Material Filter" property is now called "Material Filter Behaviour".
  • "Optimized" was removed from the options in the "Render Order" render layer property.
    • It is not needed right now, and was unnecessarily confusing.
    • In existing scenes it is replaced with "Determined by render order value".
  • The "Ok" and "Cancel" buttons in the tag dialog are now called "Ok" and "Cancel" instead of being displayed as a tick mark and a cross.

Fixes

  • A render pass rendering to the default framebuffer no longer marks its "Target" property in orange, and shows it as "Default Framebuffer" instead of "".
  • A broken render target now stops a render pass rendering to it from rendering, instead of rendering to the default framebuffer.
    • Also: the render pass shows a warning that it won't render due to the broken render target.
  • A render target now displays an error if some of its render buffers are either not valid or not set.
  • A render target now displays an error if its first render buffer is not set.
  • The sampling parameters are hidden for depth buffers.
  • Fixed absolute paths for .ramses & .rlogic files not being recognized in the "Export Project" dialog.
  • Disallow RenderPass objects being pasted as external references.
    • This is a temporary workaround and will be reintroduced in later versions.
  • Detect and remove link duplicates in the project files when loading a project. Warning messages will be generated in the log if duplicates are detected.
  • Fix bug leading to uniform properties referencing deleted texture objects. Invalid references encountered during loading of project files are discarded and a warning message is logged.

[0.9.0]

Added

  • Added first simple support for offscreen render targets, render passes and render layers.
    • It is possible to add render passes, render targets, render buffers and render layers as individual objects.
    • Render passes contain references to the render layers which they render.
    • A render layer can contain other render layers, nodes and mesh nodes which are rendered when the render layer is rendered.
      • The contents of a render layer are determined via tags: the render layer has a property "Renderable tags" which can contain any number of tags.
      • Nodes, materials and render layers also have a property "Tags" which can contain any number of tags (also cameras, but those tags are currently unused).
      • If a tag in a nodes "Tags" property matches a tag in the render layers "Renderable tags" property, the node and all its children are added to the render layer.
      • If a tag in a render layers "Tags" property matches a tag in another render layers "Renderable tags" property, the former render layer is added to the latter render layer.
      • Each tag in the "Renderable tags" list has also an order index.
        • All renderables in a render layer are rendered in the order given by the order index.
        • If a renderable is added to a render layer more than once with different order indices, a scene warning is displayed.
      • The render layers also contain a property "Material Filter Tags" and a property "Incl./Excl. Material Filter".
        • Those properties can be used to include or exclude mesh nodes based on the materials they use:
          • If "Incl./Excl. Material Filter" is set to "Include materials with any of the selected tags", the render layer renders only mesh nodes if they use a material whose "Tags" property contains a tag which matches any tag in the render layers "Material Filter Tags" property.
          • If "Incl./Excl. Material Filter" is set to "Exclude materials with any of the selected tags", the render layer renders only mesh nodes if they do not use a material whose "Tags" property contains a tag which matches any tag in the render layers "Material Filter Tags" property.
  • Added error items for broken links ending on valid properties. Only one combined error item is created for each object.
  • Added deselection in the UI - just click on an empty space in the Tree View
  • Added dragging and dropping external objects as external reference - hold the Alt key while drag and dropping
  • Limit number of entries in recent file menu to 10. Recent file menus longer than 10 entries will be truncated after loading a project.
  • Added selective import of glTF Assets. Before importing a glTF file you will be able to select/deselect individual parts of the glTF scenegraph (right now only nodes & meshes).

Changes

  • Update from ramses-logic 0.7.0 to ramses-logic 0.9.1
  • Update from ramses 27.0.105 to ramses 27.0.111
    • !!!!!WARNING!!!!! The new Ramses version has changed order of transformations (previously: first rotation, then scaling, then translation. Now first scaling, then rotation, then translation). This may affect nodes with non-zero rotations and non-uniform scaling.
  • Improved copy-paste handling in the GUI.
    • The "Paste" context menu will now be disabled in the tree views depending on the types of objects about to be pasted.
    • Changed "Paste" context menu item in the Resource tree view to "Paste on Top Level".
    • Copy-pasting will prefer Scenegraph objects over Resources, e.g. a deep-copied MeshNode that references a Mesh will not be pasteable in the Resources tree view, vice versa with deep-copied PrefabInstances that reference a Prefab.
  • The "U/V Origin" property for Textures has been replaced by a "Flip Vertically" flag.
    • Textures that had their origin set to "Top Left" in previous project versions will have the origin flip flag enabled.
  • Importing meshes is now done by tinyGLTF instead of Assimp.
    • !!!!!WARNING!!!!! Textures that are based on CTM mesh UV coordinates may have to be explicitly flipped by hand.
    • !!!!!WARNING!!!!! Shaders that rely on UV coordinates may have to be recompensated due to Assimp flipping the V coordinate.
  • Don't create engine objects for Prefabs contents.
  • Make the default resource subfolders configurable via the preferences.ini file and the preferences dialog.

  • Prevent paste from sometimes dropping links incorrectly when pasting into existing object.
  • Don't log error messages when trying to read empty files.
  • "Create node" context menu item now generates only a single undo stack entry instead of separate "create" and "move" entries.
  • Fix crash when pasting PrefabInstances containing LuaScripts which are based on external reference Prefabs.
    • Caused by incorrect modification of the LuaScript URIs during paste.
    • Old files will contain incorrect URIs. These are repaired automatically during load and warnings will be logged to the console.
    • Projects which cause "Rewrite URI property..." warnings during load should be saved to avoid these warnings in the future.
  • Fix external reference update to correctly handle simultaneous scenegraph move and node deletions in all situations.
  • Fix prefab update to handle simultaneous scenegraph move and node deletion correctly.
  • Reduce memory usage when creating undo stack entries in scenes with many links.

Fixes

  • Deleting a Node will not affect locked Property Browsers anymore, except when the Property Browser was locked onto the now deleted Node.
  • Closed docks do not get cached/saved anymore.
  • The Property Browser does not get reset anymore when pressing the Delete key while a read-only object is selected.

[0.8.2]

Added

  • The viewport background color can now be set from the project settings.
  • The Linux build no longer requires a pre-installed Qt and can be started directly with shell scripts (RamsesComposer.sh and RaCoHeadless.sh).
  • Added a default project subfolder structure.
    • Saving a project will now generate the following four subfolders in the project root folder: "images", "meshes", "scripts" and "shaders"
    • After loading a project, file browsers for new URIs will start at one of the previously mentioned subfolders, depending on what type the URI's root object has
    • The folder of the recently changed URI will be cached for next time an object of the same type needs an URI changed
    • When the URI file browser can't find the resource subfolder, it will start at the project root folder instead
    • The four default resource subfolders in the release folder have been moved from "resources" into "projects"
    • The file loader for saving/opening projects starts at the User Projects Directory, and will be cached at the folder of the last saved/opened project.
  • Added support for shared materials which are now the default for newly created MeshNodes. The MeshNode now has a "Private Material" flag which can be used to enable per-meshnode private materials reproducing the old behaviour. Loading of old projects will set the flag to private on import.
