Added Add, Subtract, Multiply, Divide, and Negate callbacks for Vector4. Also added additional callbacks for Vector2 so that all vector types have parity.

Improve performance for wireframe index list generation of polygon primitives where many vertices share points

Prevents crashing in Remesh 2.0 SOP due to non-manifold topology.

Fixed a bug where packed Alembic primitives wouldn't update properly after using the "Reload Geometry" button on the Alembic SOP

Fixed visual issues with edge selection highlighting z-fighting with wireover or wireframe edges

Parameter VOP's "Provide Menu" menu has two new entries to allow the defined parameter to evaluate as token's integer value rather than index.

Fix bug in the APEX Animate viewport state where framing with no controls selected would include the bounding box of hidden character geometry.

When a USD ROP save operation is set to strip off data from above layer breaks, the layers above the layer break would be removed from the stage, then added back to cook the next frame, then removed again, etc. for each frame. This could incur significant recomposition costs and slow the export. Now the layers above the layer break are stripped off during the save operation without altering the stage and avoiding the recomposition.

Update the help card for Karma Rayswitch VOP.

Fixed an issue where per-prim colors wouldn't be drawn on packed prims

Fixed an issue where per-prim colors wouldn't be drawn on packed prims

Fixed an issue in the Curve::2.0 state that was triggering downstream recooks when interrupting the state.

Character controls are now a valid snap target only when snapping to guides is enabled. Also fixed a bug where snapping to guides did not work snapping to other objects was disabled.

Added new option to snap to drawable geometry, defaulting to on. The snap to other objects option previously affected snapping to drawables unintentionally.

UI cleanup on the blendshape component.

Spline: Fixed a scale control that was not working. IKFK: fixed control offsets.

Fixed an issue with subframe interpolation of the bones that prevented the Otis Muscle andTissue Simulation recipe from working in Each Substep target mode in the Otis Solver.

Fixed bugs when the Otis Solver's Target Method was set to Each Substep and importing Stiffness and Damping or using an external SOP as the Constraint Target.

Fixed a bug where Mtlx Chiang Hair Roughness, Mtlx Deon Hair Absorption From Melanin, and Mtlx Chiang Hair Absorption From Color nodes always returned zero. Also fixes Mtlx Chiang Hair BSDF's tint parameters not functioning, and "Curve Direction" parameter not using the curve direction when nothing is wired in.

Fixed a bug where turning off the Enable Blendshapes display option for crowd agents did not reduce the VRAM usage if the agents had already been displayed.
