Fixed an issue with the TOP status bar drop down showing an incorrect work item when selecting items in a dynamic node, and fixed a potential crash when the status bar updates while the current scene file is being changed.

Fixed a regression in karma CPU where secondary rays from uniform volumes applied to single-sided mesh would fail to self-shadow or self-intersect. This bug was introduced in 21.0.540.

Fixed an issue logins with hkey's manual login.

Fixed an issue with logins with hkey's manual login.

Fixed an issue with logins with hkey's manual login.

Fixed missing geometry at the object level if the object had an Output SOP with only the template flag set on it.

Fixed incorrect locating of Channel List header icons.

Fixed hotl (-l, -C) failing to collapse an expanded HDA whose Contents section was saved uncompressed.

Fixed hotl (-l, -C) failing to collapse an expanded HDA whose Contents section was saved uncompressed.

Fixed a bug where husk's auto-tile stitching may change plane and channel names, and add "color" typeSemantics attribute to planes that did not originally have one defined (e.g. data planes).

Fixed an issue with the Soft Transform SOP not properly accounting for the pivot rotation when the rotates, scales and shears are all set to defaults.

Fixed an issue with the APEX Transform Handle not properly accounting for world transforms with the center scale component.

Updated the USD library to fix a couple of recent regressions in the USD rendering system.

The Sublayer, Reference, and Load Layer LOPs now use the current stage's asset resolver context when trying to resolve layers loaded by these LOPs when these nodes need to inspect the layer contents before adding them to the stage (to get the root prims or default prim path).

Added an `initialize_opengl` parameter to hou.clone.runAsClone, which can be used to cause the clone process to avoid trying to initialize OpenGL. Doing this will prevent render delegates that rely on OpenGL (such as Storm) from functioning, but can avoid issues on some headless farm machines with no OpenGL support.

Fixed a bug where MaterialX shaders for curves would fail to compile on MacOS

Fixed issue where it was impossible to change folders on the Spline Curve Clay SOP in certain configurations.

Fixed a bug where invalid data would be drawn in the viewport window for the first frame after enabling Slap Comp on MacOS

Fixed geometry light not turning the mesh into light source. The bug was introduced after recent USD changes the caused geometry light not getting detected in Karma.

Fixed a bug in karma CPU where volumes with velocity blur (under Lattice Deformation mode) would fail to render when using orthographic camera whose direction is axis-aligned.

Updated the Texture Mask Paint state to make it is easier to use with custom HDAs.

Fixed a possible crash when applying displacement to degenerate curve mesh with zero curves.
