Hi there!

I had the same problem this morning and went trying with boolean, volumemix, vdbcombine and volumewrangle.

At the end what helped me achieve what I think you are refering to is to convert the geometry that was going to be used to subtract from the imported pyro simulation using iso offset and subtracting with volume wrangle using the following expression:

f@density *= 1-volumesample(1,0,v@P);



I hope it still helps someone.
Best Regards!
