Week 4

What I did this week

• I finished the uchar attribute support in Cycles.
• Fixed some compile errors in the SSE refactor patch for Windows.

• Today I merged some of my work into master.
  • Face Normal on the Fly: https://developer.blender.org/rB49df707496e505c8a8b21c1ea36b479e950cc66c
  • uchar4 attribute support: https://developer.blender.org/rB0ce3a755f83b047f49f78da1729a73b56b9c9d55
  • AVX2 kernel: https://developer.blender.org/rB866c7fb6e63d128fa4800e28e0a091f874112344
  • Split / Combine XYZ Nodes: https://developer.blender.org/rB3de3987ea190415d0d088c3917b45f44afb43840

I fixed some last minute errors on these things while merging, especially to CUDA support.

Next week

I will look into "Store smooth normals only when used", might be a good next candidate, as this is related to the Attribute system as well.

Questions

None.
