Autodesk Released Arnold 7.2.3

Autodesk has launched Arnold 7.2.3! This release brings interesting enhancements. Let's see what's new.

The new version supports Global Light Sampling on the GPU, which enables scenes with moderate to large numbers of lights to render 2-6x faster. In addition, the distance shader has been updated to include output parameters out_distance and out_direction, which return the direction and distance to the nearest surface, respectively. The shader still returns color-mapped results by default, but the out_rgb parameter can now be used.

This release also brings USD enhancements and API additions:  

• USD Enhancements. Curves without width should render with a default value usd#1579. Support vertex UV coordinates on Curves in the render delegate usd#1435
• API Additions. A new API AiProceduralExpand expands on demand the contents of a procedural (a 'usd', 'alembic', or 'procedural' node), as it would happen in a regular render. You can use this to force the creation of procedural child nodes before the rendering starts, and to avoid race conditions when the procedurals are not thread safe.
