Fixed some blocky HQ Lighting artifacts when the light transform had scales.

Fixed a crash in HQ Lighting on MacOS due to a shader compiler error.

Improved performance of dome light texture preprocessing for non-RAT formats.

Fixed selection of lights and cameras in the LOP viewer when no other geometry was present in the scene.

Improved verbosity for cameras and light sources when karma renders with verbosity of 8 or greater. This level of verbosity should only be used when debugging scenes.

• Fixed the installer not displaying the proper supported versions of unreal (4.24/4.25 instead of 4.25/4.26)
• Fixed button parameters being triggered on first cook after loading a level.
• Added back the Static Mesh Build Settings from v1 (tangent/normal generation, lightmap index etc.)Their values can be changed in the plugin's setting dialog.
• Added back the Static Mesh Generation Properties from v1.Their default values can be set in the plugin settings, or overridden per HDA in the Houdini Mesh Generation section.

Fixed an issue where text in the TOPs work item log viewer was barely visible in the light UI theme.

Fixed a possible crash when there are multiple emissive objects that are treated as light source.

Fixed a bug where the peak usage of a license could be slightly higher then it should be in some cases.

Fixed a bug where a light guide could persist in the LOP viewer after the light is removed from the scene.

Fixed an issue with light linking affecting the headlight in the LOPs viewer.

Light and Camera LOPs now have a "Guide Scale" parameter which controls the size of the guide geometry for these primitives in the viewport. The default value for these parameters sets the value to the inverse of the meters per unit value of the stage, producing a consistent real-world size for these primitives. The camera LOP also has a parameter that can hide the camera from the viewport camera menu (in cases where the camera is for utility purposes, not meant for looking through).

Fixed a viewport bug where adding a texture to an environment light might not show up immediately in Normal Quality lighting.

Fixed bug where the light state data would improperly account for uniform scales when extracting t/r/s parms from primitive xform matrix.

Nodes other than VOPs are now able to have UT_SourceLocations to highlight their editors.

Fixed bugs where the cell input field was positioned ever so slightly off when the spreadsheet was resized or the user tabbed to the cell.

Fixed potential artifacts in light-centric sampling of geometry lights.

Fixed a Karma spotlight scaling bug (forum #76277)

Python States: LOP Light state fails to enter. [SESI #97265]

• Fix a script that was throwing an exception if a viewer wasn't found inthe current desktop.

Fixed an issue where performance monitor miscalculated time in "HQ light passes draw."

For render delegates with names that contain characters that cannot be used in file names, replace the illegal characters with underscores when generating the dialog script file paths used to generate renderer-specific parameters for the Light LOP, Camera LOP, Render Settings LOP, and viewport display options.

There was a small change to the random number generator in Karma so noise will be slightly different.

The Distant Light shelf tool used in a LOP context will now create a Distant Light LOP rather than a standard Light LOP.

Fixed a bug that was causing thrashing and invalid behaviour for the xform handle when looking through a camera or light.

Fixed the calculation of the GL spotlight illumination bounds which caused some spotlights to fail to light the scene, or be oddly clipped.
