Maya Aero simulations can be used to create effects like smoke, mist, and other gases. within Bifrost for create smoke effects. We look at collisions, emission and shading and rendering in both vray and arnold
you can create with more polygon mesh objects that you want to act as emitters. The selected meshes will all use the same emitter properties (Continuous Emission on or off, Temperature, and so on), but you can add other emitters later.
