Hello guys.

I have a very small source to emit smoke from so I scale it up and simulated it. It worked ok. Now I need get the sim back to size that the original source was. How do I do that?

Transform SOP?

I tried that but the sim disappears

right

you also need to make your volume denser since density accumulates over distance traveled within the volume
so the smaller the volume the less will accumulate and therefore the volume has to be denser for you to see it the same

so wherever you are setting up the look (on Pyro Post Process or in the Pyro Solver Look settings itself) make sure to increase Density Scale and Intensity Scale proportionally

That's great. Thx Tamte.
