Fixed an issue with shelf edits getting sometimes dropped and reset after updating Houdini to a new daily build.

Fixed an issue where editing level instances could cause a crash after commiting the data if an Houdini Asset Component was present. Ensure level instances do not cook when they are not being edited. Fixed an issue where duplicate mesh components could occur when opening a level instance containing an HDA.

Fixed an issue with Selection Sets in the APEX Animate state where pinned or isolated controls under "All Controls" would not be saved and reloaded when exiting and re-entering the state.

The TOP Geometry SOP node can now be configured to import work itesm from any external TOP network, in addition to the one already embedded in the TOP Geometry.

Added initial version of adaptive quad sizing in Quad Remesh SOP.

Updated main hotkeys documentation to include some info previously only mentioned in the What's New in 20.0.

Removed the "Pin Root" option from the ragdoll tool's settings, which had some confusing behaviour and could not vary per character. The replacement for this option is to select the root collision shape and turn off the Active toggle in its settings.

Fixed a bug with distance_pointline and distance_pointray VEX functions producing incorrect results with non-normalized direction inputs.

Fixed a bug with distance_pointline and distance_pointray VEX functions producing incorrect results with non-normalized direction inputs.

Fixed negative scales when leveling controls.

Add support for string::Format and Log for basic array types.

Fixed a bug with attributes copied from source items using the Partition Expand TOP being overwritten by dynamic attributes created on the parent partition.

Fixed an issue in the Curve state where attempting to rotate tangents of order 3 bezier curves could rotate them about the incorrect anchor point.

XPU: implemented a potential workaround for the issues we're having with NVidia 565 drivers

When cooking out of process, the Python Script TOP now has parameters for adding extra PYTHONPATH entries used for importing modules. The extra paths are added to the sys.path list automatically for script tasks created by the node.

Linear Solver: Added the ability to specify the maximum number of iterations that should be taken when using iterative or eigen solvers.

hou.SceneViewer.runStateCommand() will now attempt to send the command to the saved state if it fails to send one to the current state. This ensures that Python Viewer States receive state commands even while the view state is used to pan around the scene.

Fixed a bug in the APEX Animate state where an exception thrown during the evaluation of the scene would cause the animation to freeze.

Reverted changes to the SceneAddAnimation node so it no longer outputs a new clip, as this would unintentionally create an extra clip in existing .hip files where a SceneAnimate node already cached the animation downstream.

Added support for custom control gadgets for the apex animate state and apex rigs Added support for skin control, aka surface areas on a rig mesh that can be used as controls. Added hide/show descandant options to popup control triggers by pressing shfit + click.Hidden xform handle when the primary control is an abstract control. Added axis magnet prototype to click and drag for transform controls.

Fixed a bug in the APEX Animate state where the HUD settings were not being saved on exit if the state was entered through the pose button.

In the hotkey editor: Revert to a single filter field thatoperates on both the context and actions lists. Change the title ofthe actions list to indicate the context.

Added a segment divisions slider to the Circle Spline SOP, and fixed an issue in its state to now only show the grouped geometry in the guide drawables.

Add a new attribute to control the origin of the Instanced Static Mesh Component.
