Creating Masks and Animating them in XPression

XPression has several ways to create masks, and apply them to objects. This tutorial will show you a quick, down-and-dirty way to create a mask as a material as well as creating a feathered (soft edge) mask material and apply them to objects. Animate those objects, and the power of masking in XPression is limited by your imagination. Watch as Simon shows you the power of the mask.
