This version uses Arnold 220.127.116.11
- EXR overscan support.
- Improved sampling (textured quad lights, Cook-Torrance specular and refraction.
- Improved performance for shadow ray and rough glossy texture lookups.
- 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.
