Hi,

how can I add noise to the sparse pyro sim cache that more or less follows the movement of the sim? I know the old pyro solver has rest fields for this, which the sparse solver does not have.

I have density and velocity, is there a way to get some noise into the density field?

ok so actually it's pretty easy.
inside a volume vop, just add the velocity field to the sample position of a unified noise static and then combine it with the density volume however you like (add to sample position or multiply with density)

I tried your approach, but it can't add much detail. Can I see a sample file? Thank you very much.
