Revision bd2b1a6 by Patrick Mours (master) March 26, 2020, 12:00 (GMT) |
Fix T74939: Random Walk subsurface appearance in OptiX does not match other engines Random Walk subsurface scattering did look different with OptiX because transmittance is calculated based on the hit distance, but the OptiX implementation of `scene_intersect_local` would return the distance in world space, while the Cycles BVH version returns it in object space. This fixes the problem by simply skipping the object->world transforms in all the places using the result of `scene_intersect_local` with OptiX.
