Hopefully simple smoke question - worldyum - 10-10-2008
So I've smoke with no buoyancy so it pretty much stays put. I want the smoke to fade away (similar to what flames would do, but slower) though without keyframing its opacity. I've messed with the diffuse and dissipation settings but I'm not having any luck.

Hmm tht's actualy the way I'd approach it: diffuse and dissipation.
Are you sure that you're not emitting new smoke. I imagine you filled a volume with smoke or emitted it from geometry to get a still puff, but did you shut the emission off after that?
Re: Hopefully simple smoke question - worldyum - 10-13-2008
Yeah I shut the emission off. Maybe I just have too much smoke in general per voxel though. I'm not sure.

A good way to use dissipation is to do a sim, turn on the Show Slice with numerical values on and see the value of your smoke densities. Then use a number similar to that in the Dissipation Min Density. Thats the density it will apply the dissipation strength to. Then adjust the strength for the speed of dissipation.
