I was watching this video:
https://youtu.be/gcQrzoTniU4 [youtu.be]
and was struck by the lovely fluid color mixing in a short clip near the end (video attached). I’ve not seen fluid color mixing this realistic before and it’s an effect I’ve been wanting to create.
Anyone know where you’d go to find the “custom field advection” mentioned? Not much else is revealed about it.
Thanks,
Joe
How does one recreate the fluid effect in this SideFX video?

There's actually a Houdini help page that covers this effect specifically:

The instructions do work but they don't tell you how to take the sim data and produce the final rendered result. In addition to the usual surface volume + fluid particles, you now have a color volume (Cd.*) that you can use to color the interior of your fluid volume to show the mixing effect. I don't actually know the best way to put all these pieces together but if you do figure it out, please share it here.
