Release Date

September 19 2014

This version uses Arnold 4.2.1.2

HIGHLIGHTED NEW FEATURES

  • EXR overscan support.
  • Improved sampling (textured quad lights, Cook-Torrance specular and refraction.
  • Improved performance for shadow ray and rough glossy texture lookups.

INCOMPATIBLE CHANGES

  • Difference in microfacet BTDFs: Rough refraction viewed at grazing angles or using Phong-smoothed normals renders slightly darker now, especially for high roughness values. This affects the standard shader and AiMicrofacetBTDFIntegrate(), and fixes a bug in the previous BTDF sampling.
  • No labels
