Sardi Pax takes a look at using blender’s internal render engine to render out smoke trails using volumetrics emitted from objects in the scene.

Sardi shows how to create edit the settings of the smoke domain to develop an adaptive smoke domain for the smoke emitting meshes. Sardi also shows hot to set particles to generate a smoke variant from the system that will give a “death Eater” smoke like effect.
