The 2022.1.1 R2 update has broken motion blur for us. If the octane camera tag has a motion blur duration which exceeds 1 frame of animation, and you set the shutter to before or after instead of centered, then motion objects will have still copies superimposed over them.

Project attached.

Temporary fixes that work:

Reduce shutter time from 0.06 to 0.03 or lower. 0.006 technically covers 2-3 frames of animation, perhaps this is related and 2022.1 isnt looking forward or backward far enough anymore to get the proper motion data

Change to centered mode for shutter alignment

This problem is only since updating to 2022.1 R2 today, the previous 2022 R7 version worked fine.
