I would like to draw an object, e.g. a cube, that emits smoke from the top face only but not the rest of the faces. How can I do this?

Select the top face in Edit Mode and assign it to a Vertex Group

  • Select the Vertex group in the Smoke Flow Advanced section
  • Limit the distance of emitting from surface by setting Surface to 0.
