Newbie question I'm sure: I've got animated particles appearing and fading out using a POP VOP and I'm turning those particles into a fog VDB.
Is it possible to take the Alpha ramps on those individual particles and use them to change the density on individual voxels of a VDB? I'd like to have the VDB dissipate like the particles do.
But I can't figure out the way to map the Alpha to Density on a per particle level. The Volume VOP maps to the entire VDB.
I've looked around the internet but not found any solutions yet.
Thanks!
Take alpha from particles and use on VDB?
