The glTF exporter will now export the Pricipled Shader's Opacity value to the alpha channel of the glTF material's baseColorFactor property.

Fixes a bug in the Extract Instances LOP's action button which no longer allowed selection of nested instances.

Added a load command to the HoudiniEngineSample to load any HDA given an absolute path instead of the default hexagona_lite HDA. Source code available here: https://github.com/sideeffects/HoudiniEngineSample.

Fixed a bug with TOPs not properly storing/restoring large service memory limit values.

Fixed an issue where the Bind Pose output of the USD Character Import SOP could unexpectedly recook after changing the global time range.

Fixed bug refreshing parameter import blocks where refreshed "Label - Heading" and "Label - Message" parameters would output as unrecognized types in the dialog script and end up being loaded as float parameters.

Fixed a bug in Ray SOP to correctly calculate intrinsic UVs when projecting against a packed primitive. This was earlier reverted as it was causing issues with animation and heightfield tools, but is now fixed.

Fix crash on startup when using vulkan viewport on Linux when using AMD video card with certain driver combination. Fix crash when doing box select on AMD video cards.

The stage manager will no longer raise python exceptions if a prim's icon cannot be found. Also cache the icons to improve performance.

When switching from a LOP scene viewer pane tab to another pane tab, or maximizing a pane tab in the desktop, we now pause the renderer instead of terminating it (we still terminate if the renderer does not support pausing). This way the render doesn't need to restart when the scene viewer tab becomes visible again.

Fix issues with soloing instanceable geometry in the LOP Scene Graph Tree.

Fixed a bug in the Lattice from Volume SOP that prevented it from creating attributes for all input volumes.

Fixed an issue in point deform that was preventing it from being compiled when using a piece attribute.

XPU: fixed an issue where the lowest (ie most high-res) image would get temporarily loaded into memory for very high-res images (ie >= 64Kx64K)

Updated the ZibraVDB plugin to v1.0.8.0. This update adds local license server support and fixes a minor memory leak.

Marked the Intel Mac (x86_64) builds as deprecated. The Houdini 21.0 Intel Mac builds are fully supported but the builds will no longer be available in a future Houdini major or minor version release.

Fixed a bug in the Qt 6 build where the TOPs work item info window failed to open.

Fixed a bug in the HDA Event Script editor where script names would inadvertently change.

Added a new mode for the HOUDINI_BUFFEREDSAVE environment variable. When set to 2, the output stream for the file is not opened until the buffer is ready to be saved, which avoids corrupting the file on disk if a crash occurs during the saving process. This mode may exhibit some differences in error reporting, for example if the output stream only fails to be created when flushing the memory buffer, vs failing at the beginning of the save process.

Fixed a bug where the Gas Axis Force DOP state's HUD was missing the handle hotkey bindings.

Fixed an issue where Houdini would execute volatile view state changes for a previously released key it incorrectly still believed was held.

Fixes a bug with incorrect display of inset guides in Poly Extrude 2.0 SOP state visualization.
