C4D Deformers breaking Motion Blur

Hello all,

We have an issue with Cinema4D Deformers (Bend Deformer) while using Motion Blur. It seems that even with Tranform/Vertex selected in the Octane Tag, the Motion Blur still won't calculate properly. See the image attached...

Has anyone dealt with this? Any work arounds or advice? Thanks!

Octane 2021.1.4 inside Cinema4D R25

Are you having texture displacement? Otherwise it should work. What's the exact issue? Extreme movement? It requires higher motion data steps.

The material is displaced with a Texture Displacement and deformed, which will not render motion blur properly for that combination. Use Vertex Displacement instead, which does not have the motion blur limitation.

Thanks jayroth2020 and aoktar, you guys were quick and awesome. Yes, the problem was using displacement in addition to a bend deformer, totally user error on my part. I ended up turning off the displacement for this shot and the motion blur errors were fixed. Thank you both!
