In this recipe, we are going to see one of the most exciting effects we can obtain in Cycles—a fire and smoke simulation effect:
Start Blender and open the 9931OS_09_fire_smoke_start.blend
file, where there is the Suzanne_unwrapped object leaning on a Plane and surrounded by five small Cubes, a Spot lamp, the Camera, and a medium-intensity World with a Sky Texture.
Go to the Render window, and under the Sampling subpanel, set the Preview samples to
50
and the Render samples to100
. Then go to the Dimensions subpanel and set the End Frame to80
. Under the Light Paths subpanel, enable the Reflective and Refractive Caustics items.
