Hi-
Can anyone tip me off on how to use a group or object to control a pyro fire effect? Basically, I've applied fire to a box and I want to have half of it engulfed in large flames and the other half in small flames. I can do this in a geometry node with groups and control particles but can't seem to figure it out while using pyro effects. Any solutions?

Thanks!

you should be able to do that using one pyro solver.
Seperate the parts in SOPs (grouping or isolating with delete/blast SOP) and use two different source volume SOPs with different density and noise settings. Then in DOPs you can import the sources with 2 different nodes, merge them and feed them into the pyro solver. In those source nodes you can again control the density, fuel and velocity of each source.

best,
