Is this expected to work with fluids? I successfully used it in the past on pyro flames, but when I attempt to use it on a Flip simulation I get data but it is all weird. The Red channel has information (kind of, seems questionable), but the G/B channels are blank.
Does the direction I render from matter? I would assume the vectors are in screen space, but I am rendering from overhead which makes me wonder. Thanks for any help if anyone knows how this should work!Included the output from the renderer
