21.0.743

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).

昨日
21.0.743

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.

昨日

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

昨日
21.0.743

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

昨日
20.5.991

HUSD_Info::getLayerRootPrims is no longer a static method. Instead it requires an HUSD_Info object created with an HUSD_AutoAnyLock so it can used an appropriate asset resolver context when trying to resolve the provided layer path.

昨日
20.5.991

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).

21.0.742

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
