Simple question here. I'm just trying to dive in and understand everything better. In the creation of pyro in dops. For the source volume node. There are some different source options. “Source Smoke” …some others… and “Source Fuel”. I get the concepts of fuel, temp, volume/density. But, what are the main advantages of choosing “Source Smoke” vs “Source Fuel” or vice versa? One better for different effects? I'm assuming “Source Fuel” is better for fire…where “Source Smoke” may be better for explosions?

Source Fuel assumes you are using the Pyro Solver for combustion. Sourcing fields are fuel, temperature and vel.

Source Smoke assumes you are using the Pyro solver for smoke only (no combustion). Sourcing fields are density, temperature and vel.

Wow, Jeff Wagner. Thanks, this helps.
