Bruce Lee shows how to make a custom mask to move particles like a storm in Maya Bifrost.

Check out this new tutorial from Bruce Lee shows how you can set and use an Influence Mask in Maya Bifrost to help control particles when making a storm simulation.

Bifrost fields allow for a wide range of capabilities in Bifrost, and here Lee uses a scalar Field Scope to create an influence mask that will affect the particles as they simulate, essentially making a custom wind field.
