Blender : Animating smoke with Blender By Saraja Olivier

Start by opening a new session (CTRL+X) and delete the default plane (X-KEY). We are about to create the emitter of our particles system. The same way as we did before, we will use a circle (BARSPACE>ADD>Mesh>Circle). Once the object is added, you can leave the edit mode (TAB-KEY) and move the emitter where you want, preferably slightly over the fire emitter (for this tutorial only, we will leave the smoke emitter alone in front of the camera). If you want, you can duplicate (SHIFT+D) your fire emitter to spare a few moments. In any case, all the following steps will implicate that the smoke emitter is selected.
