Propagation/Diffusion/Filling

If there’s anyway to do this now, let me know, but otherwise I’m just asking if this would be possible or on the wishlist…

I want to have a field where if a certain channel, say Seed, is below a certain threshold, Ember grabs a value for a different channel from a point in the field where the Seed is above the value.

A bit like how PRT Volume works, where you get values away from the surface, but I know that closest point doesn’t have an analog for Ember fields.

There isn’t a full Diffusion operator yet, but you might be able to approximate it in certain situations by using a combination of Gradient and the Position input to an InputField node. Actually, the Advect node could accomplish this by wiring the “Velocity” input to the Gradient of the Advect node’s Input #1.
