Okay so I'm hoping you guys can help me. The velocity blur isn't working for a few frames that are moving pretty quickly but IT IS working for some previous frames that are moving slower (See Attached). I cranked up the blur samples and I just can't seem to fix the issue. Any thoughts on what would cause this problem?

I'm still having the issue with the velocity blur on the Volume Rasterize Attributes. Anyone have any thoughts on the issue?

It looks like you haven't computed the velocity on the first image.

What are you visualizing? It looks like your displaying the stream on the left hand side in the fist image (which doesn't have velocity computed) and in the second image you are displaying the stream to the right of it (which has a trail so I'm assuming is calculating velocity). Is that right? It's hard to tell without a wider view of your network or your file.
