More technical art!

I saw a pretty good explanation of a Silent Hill style transition material so I was inspired to try that out myself. The article in question is here: http://dp3dblog.tumblr.com/post/26742825968/thoughts-on-texture-transition-fx
But I did a change to it where I did an Add operation of the rock texture on top of the transition mask to make the glow effect match the rock texture better.

The material is connected to a Matinee that controls the transition parameter, and the Matinee is triggered by a key press through Kismet. T to make the transition, and G to reverse it.
