2023-05-15 VFX & Video


  • Habib Gahbiche
  • Omar Emara
  • Sergey Sharybin


  • Fixes and tiled compositor support was added to the Kuwahara filter patch. The main feedback so far is the performance. This is something planned to work further, but needs some changes in the algorithm itself. From artists feedback it was also not considered a stopper for merging the feature. On a technical side there is code duplication between full-frame and tiled compositor, but meeting agreed it is easier to accept it for now, until the tiled compositor is fully replaced with the full frame. The current plan is to merge the feature soon after 3.6 is branched off.
  • Kuwahara filter is planned for GPU, but it is first desirable to look into algorithm optimization on the CPU
  • Richard is investigating making audio system lazily initialized, to solve some long standing issues.
  • Omar worked on making color space conversion node working on the GPU, as well as investigating the movie distortion nodes on GPU.

It was agreed to shift the meeting by one week, to better align with schedule. We skip the meeting on the 22nd unless something important pops up.
