John Zilka takes a look at creating an underwater sand effect in Autodesk Maya by combining interactions with 3D Fluid Containers and Particles tied to some simple expressions.

how to control particles with fluids to get an underwater type effect

John covers how to use Maya Fluids fluids to control and drive the motion of nParticles, and then uses a simple expression that will control the color of each particle from a predefined list of colors. Visit John’s site for a list of the expressions used in the tutorial here.
