I know (at least I believe this to be true) that using cycles motion blur wont work with fluid simulations when rendering, however, I know that vector blurs can be used in place of motion blur.
With that said, however, I seem to be unable to get the vector blur to work in a cycles render of fluid. I have generate vectors enabled as well.
This doesn't seem to make sense to me, since vector blurs are applied after the render in compositing and therefore, in my opinion, shouldn't be affected by the rendering engine.
Any thoughts? Help?
