Arnold 7.3.7.0 Is Now Available

Autodesk has released Arnold 7.3.7.0, a feature release of its production renderer that brings improved shadows for glass objects, better global light sampling for glossy materials, faster scene IPR updates, and more enhancements and bug fixes.

Transparent objects, such as clear glass, now cast shadows. The new transmission_shadow_density parameter in the openpbr_surface and standard_surface shaders controls the appearance of these shadows.

Here's transmission_shadow_density 0 and 1 accordingly with caustics off:

With caustics:

GLS now considers material glossiness when sampling, significantly improving quality, especially in scenes with numerous small lights. While this results in minor slowdowns for fixed AA renders, adaptive renders see overall speed improvements. For instance, in the robot scene at the top of the article, a 1.7x speedup was achieved with adaptive rendering. This feature can be toggled on or off using GLS_glossy_enable.

Arnold 7.3.7.0 also features better detection of visibility changes for faster scene updates, allows to control motion keys in alembic, load and render OpenVDB points, and has improved compatibility with recent USD versions and Solaris.
