• ROP GLTF 2.0: added 'Scene Name' parameter, which can be used to name theexported glTF scene property
• ROP GLTF 2.0: added support for setting the names of certain glTFproperties (scenes, nodes, meshes) via attributes
• ROP GLTF 2.0: fixed bug in the exporter that could cause an incorrectscene graph to be exported when exporting an Object graph

Added a new viewport display option to control the maximum LOD level at which blend shapes are enabled for agents. Previously, blendshapes were only enabled for agents at the closest LOD level (0).

Added support for Unity 6.5.

Added support for Unity 6.5.

Fixed linking issues when using SYS math functions in HDK plugins.

• GLTF Animation Import: added an option to output the rest pose instead ofan animation.
• GLTF Character Import: updated the HDA to output the rest pose when eitherthe glTF file has no animations or the configured Animation ID is invalid.

Added an option on the Agent Add ML Deformer SOP to import existing blendshapes from the skin geometry rather than merging in the packed residual blend shapes produced by the ML training.

Fixed deprecation messages on nodes added early in the 22 cycle.

Fixed a bug in the SOP Import APEX Scene LOP which incorrectly added output bindings for prims which are only an input to the rig.

Added additional debugger outputs for ApexNodeId and ApexPortId types. Also, distinguished between ports which are "Not Evaluated", and ports which are evaluated but whose values are "Not Captured" as a result of not being watched.

The animation editor no longer remembers the selection mode ("Box Handle", "Box Handle with Pivot", "Retime") across houdini sessions.

The Bake Skinning LOP also now disables instancing for children of the SkelRoot prims (previously this only occurred for SkelRoots themselves) to allow skinning to be baked for any instances underneath.

Improved the performance of the animation editor's retime tool by ~19%.

The Hair Procedural now supports time sample generation for subframe sampled motion blur.

The Hair Procedural now supports time sample generation for subframe sampled motion blur.

Make sure the color for new joints makes the segment color on the apex rig builder sop

Fix a bug on the simple arm rig builder skeleton. And remove the clavicle tag. this created issues on newly created non clavicle arm setups

Update the background offset scale calculation for the screen space slider interface. Update the labels for the screen space sliders to be shorter

Hide subgraphs that are only intended for internal use

Remove a debug print and and unintentional disabled status from APEX Configure Controls SOP

Make sure that the config control icons do not scale with distance to the view. This makes the look a lot more consistant with the rig builder look.

Fixed various errors when attempting to access the menus of the apex network editor when the editor is pointing to a node which does not have a valid apex graph.

Updated the USD library to fix a regression from USD 26.03 which could cause incorrect motion blur for UsdSkel blend shapes.

Fixed a bug where HDAs larger than approximately 1GB could be saved without error messages, but reloading them would produce a corrupted asset reloaded as empty, unlocked nodes. Now, HDAs will cleanly support up to 4GB in total size, with internal sections no larger than 2GB. Saving an HDA that exceeds the supported size now fails with an error instead of writing an unreadable file. Previously written assets that exceeded the 1GB limit can now also be recovered.

Fixed incorrect normals produced by the MaterialX Bump node.
