Developing a framework for building a cascading matte effect, Dylan Winters shows how to create a rig for an alpha matte generation system in After Effects, building controls for the system that will allow you to alter the time and speed of the transition effect.
Today we’re going to rig a system that will let us quickly generate many variations of reveal mattes. It’s gonna be suh-weeeeeet
Creating a revealing matte with a cascading blind effect, Dylan shows how you are able to quickly create matte effects for transitions with controls that can be put together quite easily with a bit of expressions for the cascading effect, as well as the controls that will allow for variations in the effect.
