- Fixed several issues in ExportExactHierarchy. For Viewport and IPR rendering, this mode is enforced since Beta8
- in order to provide updates of moved geometry groups and similar scene changes.
- Fixed possible camera misalignment between viewport and final frame rendering.
- Fixed automatic detection of number of threads used for interactive rendering (Viewport or IPR).
- Fixed missing lighting update when moving a group containing light(s).
- Fixed possible color clipping artifacts in progressive rendering done with fixed point (8 or 16 bit)framebuffers.
- Fixed possible artifacts in scenes with volumetric rendering. Volume was not set correctly if shadowshaders were returning false, which in particular was the case for some Bifrost scenes.Recently added mi_ray_differential_transform function was not exported in the Plugin’s symboltable.
- For MILA layering shaders, fixed possible artifacts on thin-walled materials, and scenes withphotons/caustics.
- For MDL materials, fixed black rendering artifacts if zero-value volume absorption coefficient was specified.
