Fire

In the final shot, the Masai man is standing by a fire.  In order to create the fire, I created a small sphere which I moved to the area of the fire.

I then applied Fire Dynamics to the sphere, by going to the Dynamics tray and clicking this button.

When I moved the key frames, the sphere emitted particles, which when rendered, would form the fire.

In the Channel Box, I adjusted the Fire Scale to make it slightly bigger and more visible.

When I rendered the shot, the fire was now visible beside the Masai tribesman.
