Hello all. We're trying to render a flying bird, and the feather procedural doesn't seem to want to render with motion blur in Karma. What is the accepted workflow for getting this to work? I've tried the motion blur LOP and cache LOP to no avail. I'm assuming we need to put velocities on a certain portion of the groom in a certain way to get it to work, but so far we're stumped and on a bit of a timeline. Any help is greatly appreciated!

Hi, recent builds have a "Transfer Velocities" option on the procedural, could you give that a go? This is Feather Deform as well. All you need then is v and optionally w for angular velocity on your deformer.

Use at least 20.0.693 please, which fixes a potential bug with that option in the procedural.

Here's an example with everything set up correctly.

Amazing. Thanks so much!
