Blender Smoke Simulation - Buoyancy Density
Now, on to the Gas Parameters section! Buoyancy Density seems simple enough; the less dense something is, it should rise faster through a container of constant density. How hard could that be?
I was a little surprised that there seems to be an upper limit on how quickly this parameter will make the smoke rise. I don't see much difference between a value of 5 and 20. I suspect there are also density parameters on the fluid/smoke emitter that will work in concert, but that's a problem for future Me.
Density = 1.0
Density = 5.0
Density = 20.0
