Fixed fully transparent geometry in some MaterialX OpenPBR shaders in the ½3Vulkan viewer.

Fixed a bug in the Delta Mush 2.0 SOP's group selector callback and Edge Length method.½3

Fixed a bug in the RBD Constraint Properties SOP, where editing SOFT constraints plastic angular hardening attrib was enabled by the wrong toggle.

Fixed a crash in the ROP GLTF exporter that occurred when trying to export an animated mesh that has a changing topology between frames (which is not supported by the glTF specification). The node will now properly add an error and cancel the export.

Fi½3xed a crash in the ROP GLTF exporter that occurred when trying to export an animated mesh that has a changing topology between frames (which is not supported by the glTF specification). The node will now properly add an ½3error and cancel the export.

Add an HDK Sample called 'Merge Primitives' to show group parsing and the basic merge API in a simple SOP verb.½3

Only use output components when calculating boudning box. This should fix issues with streaming.

Adde½3d manual CE cache flush for SOP_CharacterBlendShapesCore on the CPU path, and selective flushing on the OpenCL code path.

Renamed variables and updated SOP_CharacterBlendShapesCoreCache to follow ½3the Rule of Zero.

Fixed a bug where MaterialX shader compilation would fail if the material network used a node as input for both the base shader and displacement values½3

Fixed a½3 bug where transparent materialX materials would render with noisy artifacts when in No Lights lighting mode

Added 64 bit time related structs and methods that can be used when float does not provide enough precision:

• HAPI_TimelineOptions64
• HAPI_GetTime64
• HAPI_SetTime64
• HAPI_GetTimelineOptions64
• HAPI_SetTimelineOptions64

Fixed bugs related to the APEX Scene Animate handling of multiple animation ½3clips. Clips are now stashed only when editing a clip.

Bounding box calculations for Houdini Asset Components now use outputs instead of input objects.½3

Fi½3xed a bug where the previous/next bookmark keyboard shortcuts did not work when the mouse was hovered directly over the playbar

The color range of videos exported by the internal FFmpeg backend are now ½3 limited to broadcast-safe levels (16-235). It seems like most players

expect this range and would display colors incorrectly if the video was encoded with full-range levels (0-255).

Fixed a bug where trying to load or launch an example file on a help page while using an external web browser would result in an error dialog.

The ONNX S½3OP/COP will now always falback to using CPU inference when a GPU based execution provider such as CUDA or DML fails to initialize, rather than erroring out. The error message generated by the execution provider is reported½3 as a warning on the ONNX node -- previously it was treated as a fatal error.

Fixed a bug where trying to load or launch an example file on a help page½3 while using an external web browser would result in an error dialog.

Fixed an issue with the hou.node.changeNodeType(..) method randomly failing ½3when called concurrently from multiple Houdini sessions.

Restricted constraints from operating on controls from the motion path or constraint rigs.½3

Fixed an issue with the hou.node.changeNodeType(..) method randomly failing when called concurrently from multiple Houdini sessions.

½3Fixed a number of bugs when determining to which for and if blocks an APEX node belongs. These bugs could occur when wires were drawn into a scope from outer scopes. ½3 The bug fixes also improved the efficiency of this process for graphs with

many if and for blocks such as those created by APEX Script.
