When loading a Maya scene containing a stage, possibly through other Maya reference, find the correct layer manager node for the stage. Each layer manager node is specific to the scene or reference. - Add an optional parameter to some layer manager function to specify the Maya reference that should contain the information. - Pass the correct Maya reference, if any, when computing the proxy shape node layers. - Add a unit test to load a stage in a Maya reference.
… transparency. HdVP2Material now detects when its shader's transparency is used for a geometric cut-out, such as a UsdPreviewSurface with opacityThreshold (e.g., for `cards` drawMode). In this case, transparency does not require alpha blending or depth sorting. We can setup the transparent MRenderItem to still leverage GPU instanced draw thanks to `MPxSubSceneOverride::setAllowTransparentInstances`. cf Maya API Reference: https://help.autodesk.com/cloudhelp/2025/ENU/MAYA-API-REF/cpp_ref/class_m_h_w_render_1_1_m_px_sub_scene_override.html#ab5f84f5ba90bb3caabbb69ab3d52cb37
…eview. Removes the special case for instanced render items, all objects with materials that have masked transparency are now consistently marked as opaque.
When a USD prim is transformed using a matrix, correctly read the initial matrix values when teh transform is time-sampled. Note that we still write the new matrix in the USD default value *not* at the time sample. So it only "works" like it used to "works" in the sense that when translating, for example, the other elements of the matrix are not lost, but the new value is not time-sampled. - Revert the change in the matrix implementation of the UFE transform3d interface to read the initial matrix value at the read-time not the write-time. - Currently, the write time is always the USD default-time. - Add a unit test to cover this case.

EMSUSD-1996 Fix expression UI
- Added methods on the Host class to create the data used by the UI. - Host create USD collection and string list by default. - Use the Host to create the data in the UI classes. - UsdCollectionData uses Host to create its string lists. - Make the expression widget update itself on USD data changed notification even when there is no expression attribute. - Rename the light linking custom control to be collection custom control. - Move the Maya host class to its own file. - Implement Maya-specific collection data with all needed setters. - Add a _UsdUndoBlockContext class to capture all USD changes into undo items and later transfer them to a Maya command. - Add a _UsdUndoBlockCommand that tarnsfer the captured undo items into itself for future undo and redo. - Add a _UndoItemHolder class to hold the undo items to be transferred between the Python undo context and the Maya command. - Add multiple command sub-classes so that the undo UI shows a nice and comprehensible undo name. In theory, we could have just used the existing UsdUndoBlock and that was in the initial prototype, but this makes all entries in the undo UI all be "UsdUndoBlock" which is incomprehensible for the user and does not state what would be undone or redone. Using one command per action allows the user to know what is in the undo stack.

…lete Update change processing code
- Fix setting a new prim and collection on an existing colletion widget. - Remove obsolete list item delegate and unused painters from the list view widget. - Remove unused painter function from the Theme class. - Make the data setter return true or False if the data was set or not. - (This will potentially make possible to not add an undo for do-nothing actions.) - Add validation of the prim and collection to avoid printing stack traces to the user. - Update the check condition to change include all. - Don't change focus of the expression widget on enter. - Don't allow pasting text with formatting (bold, etc) - Making the resizing of the list widgets more robust. - Added an error message when setting the expression causes an exception. - Avoid submitting the expression when it has not changed, to avoid bad interactions with undo/redo. - Move the business logic of resetting teh include-all flaginto the data class, wher eit belongs. - This avoids confusingly having two undo items when setting the expression the first time. - Also avoids having yet another "magic" callback in the UI code that would know about the business logic instead of being pure UI.

New Feature
"-root/-rt" flag (multi-use) to USD Export plugin, can be used to specify the roots/parents the exporter shouldn't go beyond them when writing out the USD, the objects/groups passed to the root arg then becomes at the root of the written USD.
Enhancement:
exportSelected flag now will export only the selected objects and their children, all parents above the selected objects will be ignored unless requested via the 'root' flag.
To achieve the old behavior the 'exportSelected' flag used to do before the implementation of the "root" feature, a pipe "|" can be passed to the root flag, this will export the selected objects under all their parents up till the scene top root::
