Mentelray for Maya也更新至mental ray 18.104.22.168
- Progressive rendering in the IPR is more responsive now, especially when finalgather is off
- Refractions and reflections are enabled for maya_volumefog
- Deforming animation in Alembic files imported using GPU Cache is fixed for batch rendering
Fixes in the mental ray core:
- Unified sampling: fixed possible crash if coverage framebuffer was used in combination with unified sampling

- Stabilize flushing mechanism for rendering very large scenes.
- For layering material shaders (MILA), added support for back_scatter LPE pass.
