Motion Blur generates anomalous frames

[Arzillo]

I have a problem with motion blur... every so often in an entire animated sequence a couple of random frames behave abnormally. It almost looks like the subject's legs are moving very fast, but as you can see from the same sequence without the motion blur the legs barely move.

Purely out of curiousity: Your characters topology is not changing during the animation (polygon count)?

[Arzillo]

no, nothing changes, however I solved it in a different way and that is by fixing the animation with alembic, now everything works but the problem remains. I'm using Cinema 4D so the problem could be in the interpretation of Corona with Cinema animated frames.

Hi there, are you able to share your scene with us to test?

Also, out of curiosity, how are Cinema's other render engines (either standard, physical, redshift) results look like?
