- Updated to Arnold 188.8.131.52.
- Light portals: skydome lights can now use portals to reduce noise for interior scenes, where light comes in through relatively small openings. Light portals are regular quad_light nodes where the new parameter "portal" is enabled.
- OpenVDB motion blur optimization: faster rendering of motion blur from physics simulations, between 25% and 80% in test scenes with strong motion blur. The new velocity threshold parameter controls filtering of noisy/extreme velocities.
- Volume shader support for SDF (Signed Distance Function) grids.
New core AOVs available: diffuse albedo, shadow matte.
Added a detailed texture statistics diagnostic flag.
