The last thread on this topic I can find is from a couple years ago, and I’m wondering if there has been an updated processes for mapping a texture on FumeFX using the Krakatoa FumeFX PRT.
I simmed with Fluid Mapping, but its not really what I’m after. I’m looking to transfer UV mapping coordinates onto the particles at their birth and then have then retain that pixel value.
Bobo, I’ve seen a couple different approaches, but since the PRT FumeFX is much newer, and Magma has updated quite a bit, I am hoping that maybe a more streamlined approach has developed.
PRT FumeFX is the wrong tool for this because it performs a history-independent sampling of the current frames’ Fume grid. So there cannot be any “memory” about what a “particle” looked like at birth - every particle is generated independently at the current frame and then completely new particles are created on the next frame, one (or more) per voxel…
Stoke particles advected by FumeFX can acquire any value at birth and keep it throughout the simulation though. So you might have to look into Stoke. I am pretty sure it could be done with ParticleFlow+FumeFX Follow, too.
