How to control the speed of smoke?

Support Basics & Interface

I followed this tutorial, but nothing is said about how to slow down or speed up the smoke, in order to control how slow or fast the smoke behaves?

Anyone could help?

Thanks,

If you double the life and halve all the forces and initial speeds (in this case just Rand and Force Z) then the particle system will run at half the speed. You might need to tweak Tot as well, or change the start and end frames too.

don’t forget damp, which slows down particles over their lifetime, which I’m assuming would be useful for some types of smoke.

Ok, let’s give it a try…thanks, blendermates!!!
