I am trying to deform a basic smoke simulation I did with the new "Volume Deform" node. However, it seems to error out unless I strip it down to only one field, ie "density" or "vel.x" ect. The problem is, I want to use the vel of my deformed smoke to drive particles. Is there anyway around this? I made three duplicates of my volume deform tree and merging back together for each vel field, and am caching it out, but it is super slow. Thanks.

Volume Deform will deform as many volumes as they are present using single lattice, what error are you getting?
