  • Patrick Mours (NVIDIA)

Blender 2.93

  • Both Cycles and Eevee/Viewport have some high priority bugs remaining. Clément and Brecht will work on fixing them in the next few weeks.
  • There is one important issue with crashes on selection on NVIDIA cards. Patrick and Clément have tried to reproduce this but have not succeeded so far. We’ll try with more hardware variations, scenes, drivers to find it, and also ask users for help to pin down the exact setup that causes this.

Blender 3.x

  • For both Cycles and Eevee there will be blog posts explaining plans for the Blender 3.x release cycle, in the next few weeks.
  • Kévin will look into OpenSubdiv for the viewport. Clément suggests to do this with compute, which makes it a more isolated changes and improves performance with progressive samples, as opposed to doing it as part of shading in the 2.7 implementation.


  • Sergen at Tangent is working on improved volume rendering. Brecht is interested to see the designs/code and provide early feedback, Stefan will provide a link.
  • Edoardo is working on point cloud rendering support for discs and opacity attributes.
  • The Cycles rendering developer job offer was removed from blender.org, as we are close to hiring a candidate.
