Reply To: Motion Blur creating crazy render times. (Cycles)

Hi Matthew, when your Frames look like the one above, you should use at least version 2.83 and enable Adaptive Sampling:

This will render the background with only 1 (or at most just a few) Samples and use 1500 Samples only where needed.

Also, if you enable the Vector Pass, you can use Vector Blur in Compositing.

A bit less quality than real Motion Blur, but a lot faster (haven’t tried this myself…).
