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

Motion Vectors had a bug where if your camera was not facing -Z, the rendered results would be wrong. But this has been fixed since Labs build 18.5.645. Could you try again with the latest build?
