Fixed a bug where the geometry inputs for a modifier HDA were always being disabled and greyed out. Now only the first input will be disabled because it is reserved for the object that the modifier is applied to.

Fixed the Houdini PyImath libraries so that they have a custom "_sidefx" suffix in their library names. This helps avoid conflicts with system PyImath libraries.

Fixed an issue with hkey where preferences required a restart.

Unify the use of the term "Data Set" in parameter labels of ML Train Neural Cellular Automata and ML Preprocess/Train GSplats TOP nodes replacing the previous "Dataset".

Added clearer error message to ML Train Gsplats logs, when detecting GPU architectures incompatible with installed PyTorch or CUDA versions.

Fixed a bug in the glTF importer where it mapped the specular color factor in materials to generic 1,2,3 channel names instead of the Houdini r,g,b color channel names.

Introduced new parameters for controls over the Ray Directions on the Cage Mesh on Bake-Pre Process COP and SOP, which by default sets their directions to their topological match on the Low-Resolution.

Fixed a bug where ML Train Gsplats failed when running on multi-GPU linux systems.

Added support for the glTF diffuse alpha, occlusion texture strength and normal texture scale material properties to the Mtlx glTF Material.

Refactored ML Train Neural Cellular Automata TOP hutil training scripts; no user-facing behavior change.

Backported doc update - Edit LOP's edit-retargeting instructions and removed unused parm details.

Backported updates for RFE 156531 Added files for Re-target Transforms pane in Edit LOP. Updates to enable Re-target Transforms pane in Edit LOP Added button delete edits with incorrect paths Added button to remove all unused edits Removed refresh button and added a callback to refresh when delta parm is edited Added undos for all ops

Updated Houdini's USD library to incorporate a fix for https://github.com/PixarAnimationStudios/OpenUSD/issues/4069 which would cause prims to get stuck in bounding box draw mode.

Fixed a bug in the PointInstancer LOP where when targeting prototypes already under the Prototype Root prim, they would get pruned by mistake.

Fixed a bug in the glTF exporter where it only exported the material transmission factor if a transmission texture was specified. The glTF specification allows for a transmission factor without a transmission texture.

Fixed a bug in the new UI where applying a stylesheet to a Qt tab widget, and resizing the shown widget to its minimum size would cause Houdini to crash.

Fix potential crashes when right-click on geometry (aka APEX) channels in the channel list.
