Gaffer 1.4.0.0b1
Pre-release
Pre-release
Note : This release introduces
linux-gcc11
builds which are only compatible with Linux distributions using glibc 2.28 or higher.
These specificlinux-gcc11
builds are intended for testing purposes while we upgrade our toolchain and dependencies to better align
with VFX Platform 2023, and should be considered "beta" in advance of a stable release in Gaffer 1.5.
Known bugs : Gaffer may crash when stopping an InteractiveCyclesRender with the CPU device and SVM shading mode. A fix is in progress.
Features
- Cycles :
- Updated to version 4.0.2.
- Added support for CUDA and Optix devices (GCC 11 builds only).
- Dispatcher : Dispatchers are now TaskNodes, allowing them to be nested in a task graph. Possibilities include :
- Using a LocalDispatcher and a Wedge to launch multiple TractorDispatcher jobs.
- Using a nested LocalDispatcher to perform a group of tasks on a single blade within a TractorDispatcher job.
- DeepSlice : Added a new node for clipping out part of an image based on depth.
- ImageInspector : Added a new panel for inspecting image format, metadata and channel statistics.
Improvements
- Arnold : Gaffer's native OpenColorIO config is now automatically translated to Arnold. Use an ArnoldColorManager node to override this behaviour.
- Toolbars : Changed hotkey behavior to toogle any tool on and off. Exclusive tools such as the Translate and Crop Window tools activate the first tool (currently Selection Tool) when they are toggled off.
- CropWindowTool : Added
Alt
+C
for toggling both the crop window tool and the relevant crop windowenabled
plug. - TaskList, FrameMask : Reimplemented in C++ for improved performance.
- LocalDispatcher :
- Added a new dockable LocalJobs editor, to replace the floating window previously accessible via the "Execute/Local Jobs" menu item.
- Task output is now shown in the UI.
- Jobs are no longer removed from the UI as soon as they complete.
- Incomplete jobs are now killed automatically when the application is closed, after prompting to confirm that shutdown should go ahead.
- Cache : Increased default computation cache size to 8Gb. Call
Gaffer.ValuePlug.setCacheMemoryLimit()
from a startup file to override this. - Dispatcher : Reduced internal overhead of
dispatch()
call, with one benchmark showing around a 3x speedup. - ScriptWindow : Added "Save" option to dialogue shown when closing a window containing unsaved changes.
- Resize :
- Added support for deep images.
- Added "Nearest" filter.
- Shuffle :
- Reimplemented to match ShuffleAttributes and ShufflePrimitiveVariables.
- Any number of shuffles can be added using the UI.
- Wildcards can be used to match multiple source channels, and expressions can be used to map them to destination channels.
- Source channels can optionally be deleted after shuffling.
- Overwriting of destination channels can optionally be avoided.
- Added
missingSourceMode
plug to determine behaviour when a source channel doesn't exist.
- Reimplemented to match ShuffleAttributes and ShufflePrimitiveVariables.
- NodeEditor : Improved image channel selectors :
- Added "Custom" option, to allow strings to be entered manually.
- Added right-click context menu.
- Switch : Added
connectedInputs
output plug. - Backdrop : Improved drawing order for nested backdrops :
- Larger backdrops are automatically drawn behind smaller ones, so that nested backdrops will always appear on top.
- Added a
depth
plug to assign a manual drawing depth for the rare cases where the automatic depth is unwanted.
- ImageStats : Added
areaSource
plug, allowing area to be driven by the input display window or data window. - 3Delight :
- Added camera overscan support.
- NSI scene description export format is now based on file extension -
.nsi
for binary and.nsia
for ASCII. - Added support for reading
dl:
anduser:
attributes from shaders. - Added
importanceSampleFilter
plug to DelightOptions, providing denoiser-compatible output. - Matched DelightOptions default values for
oversampling
andshadingSamples
to 3Delight's own default values. - Added support for external procedurals.
- GraphEditor : Improved logic used to connect a newly created node to the selected nodes.
- ScenePlug, ImagePlug : Child plugs are now serialisable. Among other things, this enables them to be driven by expressions (#3986).
- Premultiply : Added
useDeepVisibility
plug, which weights samples according to their visibility based on the opacity of samples in front. - CyclesOptions : Improved device selection UI.
- ImageReader : Improved multithreading of EXR reads. This can result in a performance improvement of around 4X for large images.
- Added OIIO config that disables OIIO threading by default. This simplifies our threading model, and has no impact on performance for our main use cases. If read performance of Gaffer compositing using non-EXR formats, such as Tiff, is important to you, you may want to add your own config to turn OIIO threading back on.
Fixes
- BackgroundTask : Fixed potential deadlock caused by destroying a BackgroundTask from Python while it was still running.
- Dispatcher : The job directory is no longer created when dispatch is cancelled by a slot connected to
preDispatchSignal()
. - LocalDispatcher :
- Fixed delays and zombie processes caused by shutting down Gaffer while background jobs were running. Background jobs are now killed before Gaffer exits instead.
- Stopped failed jobs jumping to the end of the Local Jobs UI.
- Fixed message log update.
- Fixed
Job.statistics()
errors on Windows, ensuring that apid
is always returned when available.
- ImageStats :
- Fixed output of infinite values, which were previously being clamped.
- Results for min/max now correctly reflect zero values outside the data window.
- NodeMenu, NodeEditor :
userDefault
metadata is now evaluated in the script context, so it can depend on script variables. - 3Delight : Fixed loading of surface shaders such as
dlStandard
so that they can be connected to the inputs of shaders such asdlLayeredMaterial
. - DeepState : Fixed handling of
NaN
values and samples whereZBack
is less thanZ
. - Premultiply : Fixed handling of non-existent alpha channel.
- PlugAlgo : Fixed promotion of CompoundDataPlugs with non-dynamic children, such as the
Camera.renderSettingOverrides
plug. - ColorToVector : Fixed parameter types.
