Smoke with Particle Age and Facing Particles

Our smoke is base on “facing” materials emitted from a super spray. The faces always turn to meet the camera or perspective view. Particle MBlur does not work with facing particles, so we will be using an opacity gradient map instead. Here it is before opacity materials are applied, then complete.

Here are the super spray settings:

The material, which is half the story:

FACE MAP is essential!

The diffuse particle age map is unchanged from the defaults.

Here is the opacity radial gradient:

Now make your own colors in partcle age and particle settings/forces to create wind, fire, etc.
