Update USD library with fixes for material display on point instancers, improved performance of editing instance xforms, respecting umask when writing USD files, and trying to reduce spurious failures when trying to write USD files to network shares from Windows.

Clean up lightmixer node warning and error.

Fixed a bug where Mtlx Normalmap was using incorrect tangent space. Mtlx Tangent and Bitangent nodes now compute tangents based on UV (if the uv attribute exists) instead of simply returning primitive dPds and dPdt.

Updated the Make Smooth and Make Balanced operations on Curve-2.0 SOP to first expand the tangents of selected points if needed, and improved the creation of arcs in draw mode to work following collapsed points if possible.

Fixed some viewer shading issues with metallic environment light reflections in HQ Lighting mode.

Fixed issue with 'uint' and 'uint64' types in the USD shader translator.

(MacOS) Fixed an issue that Houdini installed by launcher was missing top-level symlinks in Houdini.framework.

Topo Transfer H19 help card updates and cleanup: added example file, added improved images, removed some outdated images and broken compare/tab/video widgets.

The USD Render ROP no longer flattens all sublayers when generating its temporary files for rendering. It only flattens implicit layers. The resulting stage should be identical, but the size of the temp files should be much smaller.

In the AssetGallery, add a file chooser button to choose the gallery db. Add QT_GalleryModel::updateFromSource() which will bring the model's caches in sync with its data source.

Fixed an issue where resources created by NodeSync (i.e. materials) would be met by a null ref error.

Fixed a macOS-only bug where the HDK Makefile.osx file contained bad __MBSD_TARGET_VERSION__ tokens that prevented the file from successfully building plugins.

Added "Automatic Headlight Creation" render property.

The Transform Pieces SOP now supports using the standard 'transform' matrix3 or matrix4 attribute on the template points.

Renamed the Broken Points parameter on Curve::2.0 to Corner Points so that it is consistent with the naming elsewhere in the tool.

Updated the Rig Pose viewer state to add guide geometry for enforcing rotation limits and to update the method that is used for enforcing the rotation and translation limits. Instead of simply acting as limits on the paramters, rotation and translation limits are now applied as if the skeleton were being posed from its rest pose, regardless of the posing mode that is being used.

The custom output parameter on the ROP Fetch TOP can now be set to a space- separate list of parm names, instead of just a single parameter. This makes it possible to cook a chain of ROPs where multiple nodes have a non-standard output parm name.

(MacOS) Fixed an issue that uninstall HQueue left behind some files.

Adding option APIKeyFile as a replacement for HOUDINI_API_KEY_FILE in hserver. On windows the location of houdini.env is different for hserver since its run as a service. This makes it difficult to change options and isnt immediately obvious hserver uses a different houdini.env. To fix this APIKeyFile in houdini ini file should be used to specify an API key file. This option can point to the same file as HOUDINI_API_KEY_FILE.

(MacOS) Fixed an issue that Launcher was unable to override the HQueue installation done by old Houdini installer.

Removed bendfactor for Unity versions 2020 and up because it is deprecated.

Fixed a regression with tag visualizers on bones, lights, and cameras.

Fixed a viewer crash when toggling Load Payloads in Viewer off, then on again.

Fixed bug where the motion path handle accessed an uninitialized member.

Adding command line options `--storage-location` and options file `storageLocation` to optionally set the persistent storage location used by hserver.
