Fixed a bug in the Light tool that could result in the view direction being unexpectedly reset.

Fixed a bug in the Lookup CHOP's "All Lookup Table Channels" mode where it produced slightly different results from the "One Lookup Table Channel" mode, due to an off by one error when mapping the index range to the lookup range.

Fixed bug where deleting a light mixer would cause other light mixers to throw python errors due to hou.ObjectWasDeleted error.

The light LOP will no longer show the guide scale parameter when not in distant or point light mode since the dimension parameters will override the guide scale.

Fixed a bug where syntax highlighting in the textport could access freed memory.

Fixed a visual bug with environment lighting in normal quality lighting when a material had a diffuse texture.

Fixed an issue with spotlight shadowing in the viewport that could cause excessive shadowing.

Added the Copy Property LOP that copies attributes from one prim to another, or from one name to another on the same prim. Provide tab menu tools to convert light primitives to/from the new attribute names introduced in USD 21.02, so that Houdini (which uses USD 20.08) can load USD and accurately display files authored with newer USD libraries.

Fixed a bug where the light state placement modes were clobbering the scales on lights.

Lights with textures specified as relative file paths now work properly with Houdini GL and Karma render delegates.

Improved the rendering performance of the TOPs work item dependency graph lines and work item highlighting, when a large number of highlighted work items are visible at the same time.

Version 2:

• Optimized reading of attributes.
• Fixed a bug preventing changing MeshGeneration properties via the details UI.
• The plugin now logs the detailled connection error when failing to create a session.
• Fixed a possible instantiation loop when rebuilding a loaded indie HDA without an indie license.
• Fixed the Houdini Engine status incorrectly reporting a license failure after attempting to use an indie asset with a commercial license.
• The plugin is now using the HAPI GetStringBatch() function when retrieving string arrays from HAPI.This is slightly faster than retrieving each string separately.
• The plugin is now using HAPI's LoadGeoFromFile() function when importing bgeo files instead of manually using a file sop.

Fixed a bug where bsdf-centric sampling of area lights would write incorrect values in unshadowed AOV and result in bogus shadow matte.

Fix python exception if no prim is selected in the lightmixer state.

Geometry light now uses render visibility flags on the geometry to enable or disable lighting components in order to better match the render with geometry light disabled.

A chain of SOP Import LOPs set to "Copy Contents into Editable Layer will now properly give each LOP a different "active layer" highlight color (since each one adds a new layer).

Ensure that invalid transforms won't be created when a lightmixer node is created, regardless of the prim type selected.

Fixed some issues when looking through a light in the LOPs view with a render delegate other than GL, which most delegates don't recognize as a valid camera.

Fixed a slight brightening of images, especially in dark areas, when using log-sampled 1D OpenColorIO LUTs.

DXF support has been slightly improved. Will ignore OBJECTS and THUMBNAILIMAGE sections rather than failing. Will import LWPOLYLINE entities.

Fixed a recent regression that caused a crash in the LOPs viewer with lights.

Fixed a bug where Karma treated textures on all lights as environment maps.

Fixed a bug with volumes and lighttree

Version 2 :

• Fixed crash when Baking landscapes with PDG.
• Fixed bug causing invalid transforms on Static Mesh Component uponmultiple bake.
• Fixed position offset on Landscapes due to Heightfield tiles havinga slightly different size.
• Fixed the GeneratedDistanceFieldResolutionScale Static Mesh GenerationProperty not being properly applied before building the Static Mesh.
• Fixed Generic Attributes not being applied on the Houdini Asset Componentlike in Version 1.
