Wanted to explain how I set this up, because some people on twitter were asking, but also for future reference for me when I eventually forget how it works. Very ramble-y, watch in x2 speed or something.

If you have any questions message me on twitter   / dmeville  

Edit: Correction at 44:10 I think part of the reason why the exported texture looks different is because we left in the "AttributeWrangle4" from the velocity export, which remaps Cd and we DON"T want to do this for density (because we already do this on the volume slice). Oops!
