Autodesk has launched Arnold 7.2.3, a feature release. Let's see what's new.
In the new version, Global Light Sampling is supported on the GPU. Global Light Sampling is now available for GPU rendering, which allows scenes with moderate to large numbers of lights render 2-6x faster.
In addition, the distance shader has been updated, adding out_distance and out_direction output parameters, which return the direction and distance to the nearest surface, respectively. The shader still returns color-mapped results by default, but now the out_rgb parameter can be used.
Multiple outputs are available for shading state shaders, allowing a single state shader to have multiple output connections in a shading network.
There are also USD Enhancements and API additions. To learn more, read Arnold 7.2.3 in the online documentation.
