Houdini Niagara: Optimized some functions to use a binary search instead of a linear search. This will drastically improve performance when using "lengthy" point caches. Added binary search to the CPU and GPU versions of the following functions: GetSampleIndexesForPointAtTime, GetPointIDsToSpawnAtTime, GetLastSampleIndexAtTime.

Updated the Agent Edit SOP, Crowd Trigger DOP, Crowd State DOP, and Agent Clip Layer DOP to add the standard button for creating spare parameters from ch() expressions in their VEX snippet parameters.

Fixed a bug in the macOS HQueue Client install script where the script created a LaunchDaemon service that failed to start the client. The bug occurred only in the install script installed by the Python 3.10 installer and not by the Python 3.9 installer.

Fixed several issues with joints and skinning being imported to Unreal incorrectly. Added support for material import for skeletal meshes. Added baking support for skeletal meshes.

Corrected a bug in the Texture Mask Paint tool that corrupted the display of the mask.

Houdini Niagara:

• Fixed an issue that caused particle count to drastically increase whenmultiple instances of a Houdini niagara emitter were placed in the world.
• Re-imported the example P_on_surface Point cache, as it seems it wascorrupted in recent versions of Unreal

Fix an issue with the Curve state where pressing the T/R/E keys with the transform handle hidden would jump out of the state into a move tool. Pressing these keys now shows the handle and switches it to the desired mode when in edit mode, and consumes the key without exiting the state otherwise.

Fix issues with translating black-boxed shader HDAs to USD.

The Blendshapes 2.0 SOP now supports double precision float attributes when Cache Input Deltas is disabled.

The Blendshapes 2.0 SOP now supports double precision float attributes when Cache Input Deltas is disabled.

Fixed an issue in the POP Steer Obstacle DOP which could cause incorrect "references to nodes outside the subnet" warnings when saving an HDA containing this node.

Added back the unity plugin package to the installer/launcher.

• Added a timer to prevent updating session sync assets too frequently,as this can cause issues with very large HDAs that contain a lot of nodes.
• Added new console variable "HoudiniEngine.LiveSyncTickTime" that can be usedto set the value of the above timer (default is 1s).

Fixed bug in the Edit SOP where we used the world origin instead of computing a local origin for the oriented bounding box local frame in the degenerate case of a covariance matrix with a single eigenvalue.

Fixed an issue with running HQueue clones on Windows machines.

Added a new constructor for hou.AgentClip which loads a clip from a skeleton primitive on a USD stage.

Float ramps: improve the stability of editing ramps with Bezier interpolation that have many points.

Fix crash when hitting Esc key while the DeltaMush SOP is cooking in some situations.

Fixed a bug where Coordinate System LOP would use render camera's aspect ratio instead of projection camera's.

Fixed making black-boxed asset for MaterialX shader VOP HDAs.

Fixed an issue where the Unpack USD SOP did not allow enabling the Name Attribute parameter without also enabling the Path Attribute parameter.

Fixed several potential crashes with unpacking packed USD primitives, when standard attributes from the primitive's schema had an incorrect number of values (e.g. the 'velocities' attribute for point-based prims).
