- No high priority bugs remaining for 2.93, so no code changes expected at this point.
- 3.0 release is likely to move a few months later, so Cycles X might be ready in time for that.
- Cycles X: main new development is removal of the megakernel and some further GPU performance optimizations. This also reduces OptiX runtime compilation time to less than a second, as only the simple intersection kernels need to be compiled. Main focus this week is to bring back some features like shader ray-tracing and baking.
- Sergen worked on adding indirect light in his delta tracking implementation.
- Edoardo was looking into transparency efficiency for point cloud rendering, perhaps doing shading in the intersection function and ensuring good sample stratification.
- Kévin is finishing various patches for the Alembic procedural and OptiX BVH performance.
- Jeroen works on mesh drawing performance for mesh editing, together with other developers as part of a mesh editing performance project announced on code.blender.org.
- Kévin is rewriting his initial code for OpenSubdiv support on the GPU. The batch cache for OpenSubdiv needs to be different than for regular meshes to preserve all the required connectivity, so this involves a fair amount of work to add a new batch cache backend.
This is a weekly video chat meeting for planning and discussion of Blender rendering development. Any contributor (developer, UI/UX designer, writer, …) working on rendering in Blender is welcome to join and add proposed items to the agenda.
For users and other interested parties, we ask to read the meeting notes instead so that the meeting can remain focused.
