2022-8-9 Render & Cycles Meeting


  • Brecht Van Lommel (Blender)
  • Christophe Hery (Meta)
  • Brian Savery (AMD)
  • Nikita Sirgienko (Intel)
  • Patrick Mours (NVIDIA)


  • 3.3 status: fix for ray-tracing precision is being committed. Besides that no regressions blocking the release, though still planning to work on bug fixes in the next few weeks.
  • Intel OneAPI: ahead of time compilation still waiting to be enabled, in the short term this will require new hardware for the buildbot. Compiler optimizations may take a while since right now these are not working without performance regressions.
  • AMD HIP: fix for texture resolution bug expected for ROCm 5.3 in September.
  • Path Guiding: patch was updated, Brecht will review.
  • Many Lights Sampling: adaptive splitting with importance resampling was implemented, seems to help in some cases but still issues to be investigated.
