Tweak smoke

My explosion won’t look right without the smoke looking good. To tweak the smoke, go to Simulation>fuel and turn on Fire Creates Smoke. This make the smoke react really nicely to the fire. You’ll also find Smoke Density under that, plus a tab dedicated to Smoke. The settings in there are fairly straightforward. Smoke Buoyancy, for instance, makes the smoke rise up; Dissipation Strength controls how quickly the smoke disappears. Again, experiment with the settings.
