Ramiro Fernandez shows how to create storm clouds in After Effects, using the popular particle generator, Trapcode Particular. using his creation as the example, Ramiro walks us through how he create a close camera pull through fairly realistic looking storm clouds.

Any (modern) particle generator will be able to create this effect, and Ramiro walks through the sprites he uses to achieve the storm clouds, complete with internal lighting, lighting up parts of the cloudscape.
