软件更新：
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.
