Hey Everyone,

I had this working at one point. For some reason I can't get the vector blur to render out on H15. I did a bit of googling and found a thread with an example file. Using the example file, I can get the mantra node to work, but if I try to add a new mantra node and output the same aov it no longer works. Is there a new method of outputting vector aov?

I've attached a file showing the old mantra node working. Maybe I'm just missing a step.
:?:

Using the old mantra node, you didn't need to enable geometry blur on the objects being rendered. I guess it was being calculated internally. I enabled geometry blur and it works.
