Attributes merged using a partitioner node can now be configured to preserve array size, instead of always merging into a single scalar value.

Fixed a viewer bug where using an image for a texture and a background could cause the pre-processed texture image to affect the way the background was displayed.

Fixed a bug where VEX trace() and occlusion() ray visibility was tied to primary visibility.

Fixed a bug in MotionClip Evaluate and MotionClip Extract which would cause attributes to remain on the evaluated geometry when the "Unpack Attributes" parameter was changed or toggled off.

• Fixed an issue where the Houdini Engine Tools with both HDA and Mesh input would not assign both inputs correctly.
• Mentioned the documentation in the Visual Scripting example scene.

Fixed a bug where the StaticMesh translator would read point attributes from an incorrect point index.

Fixed a bug with baking static mesh outputs where temporary complex collision meshes (the collision_geo group) would not be baked.

Muscles, Tissue, and Skin now use the Scale-Invariant ARAP model for tet-stretch, triangle-stretch, and fiber constraints by default. As a result, stiffness values need to be adjusted (increased) accordingly.

Fixed width of edge selection lines on MacOS, which varied depending on the scale of the geometry, rather than remaining a fixed pixel size.

Fixed noisy direct lighting in reflection component of MaterialX implementation of Standard Surface when the material is transparent and Direct Refraction Subset property is set to "Outside" (default value).

Fixed display corruption with polar maps used by GL which were larger than the maximum 2D texture size display option.

Added a shading quality multiplier setting to Karma.

Fixed a bug that could cause Houdini to incorrectly think file permissions do not allow the user to open an Alembic archive.

Added pdg scheduler service interface.

Improved compiler threading performance for Karma XPU.

For Windows, added access method (HOUDINI_ACCESS_METHOD=3) that is the new default. This particular method uses the CreateFile() Windows API which hopefully gives better behaviour for testing whether files/directories have read/write/execute permissions, especially when dealing with network storage devices.

The Vellum Constraints SOP has a new Model menu, replacing the Use Linear Model toggle, for the Triangle Stretch, Tetrahedral Stretch, and Tetrahedral Fiber constraints. The new option called Scale-Invariant ARAP takes into account the area of triangle or volume of tetrahedron when considering stiffness, making stiffness values work much better across physcial scales, and is the best option for organic materials such as skin and muscle.

Added new node bundle filters to TOPs for the specific PDG types (Scheduler, Processor, and Partitioner).

Fixed a bug causing the plugin to create an extra empty Blueprint when importing BGEO files.

Fixed an issue where PDG callbacks were being called in inappropriate times if there are multiple output objects

In the Mocap Steam SOP, fix spurious reconnection errors when the mocap device sends data too slowly (5 FPS or less).

Fixed a bug where unicode characters produced an error when entered in sticky notes in the Network View.

Fixed an issue where output colliders with no mesh renderers would result in a disabled Collider

Slight tweak to the lookat vector handle from the camera/light PIs to compute screen space distance from the tip instead of the pivot to let MMB indirect drags distinguish between the pivot and vector handles.
