Hi Mars,

One idea would be to bake the RS Material and use the image (still or sequence) to drive this with a Displacer.
The Information that feeds into the RS Displacement (Like Maxon Noise) is fed into the Emission channel.
An AOV is set (direct output).

As usual, I checked the current version and practically recreated the idea.

It is not a one-button push action, but I hope faster than recreating a whole Material.

All the best
