hi,

i have a cached smoke sim and a cached advected particles sim from that smoke sim.
the particles have color by nage, so they are red at beginning and green at the end…
now i need to transfer this colors to the smoke so i can use the colored smoke as a rgb matte for further modification in post…
is there a way to colorize the smoke after caching with the advected particles colors?
any hints are welcome…

ok,

i think i found it out…

volume_from_attribute…
also a volume blur helps also to get smoother color transitions…
