Camera Motion Blur is currently broken

Hey all,

Just trying to get awareness of the current bugs - T55626 and T55106 . This has been an issue since March.

I tried to have a look at the code but don’t really have an idea on how the camera data is stored in cycles / how to reset the transformations on frame change.

The current work around methods are:

  • Disable Persistent Data
  • Change motion blur from center of frame to start of frame / end of frame
  • Reset blender for each frame rendered.



I’ll try to have a look at it soon.
