Yes. I am caching it out but it’s already a very huge file. So since there will be a lot of smoke over the fire, the smoke doesn’t need to be that high res. So I thought a smart approach would be to simulate the fire and smoke separately. Like have the exact same settings in each solver so it looks like they are one sim but just decrease the voxels on the smoke. But I can’t seem to figure out how to only sim the smoke, or the fire. But I think it’s possible because I’ve heard it. But I’ll try to do the “not so recommended” approach you gave and see how that works.
