Screen transition using material effect?

I’d like to know if someone can help me with a screen transition using a material instead of a GUITexture. I’m trying to create a wipe transition, but using the Alpha Cutoff parameter in the material to create a dissolve effect.

I’m assuming this would involve putting a quad onto the screen with the material and animation when the scene changes.

I’d go the easier route. It would be easier to code as well as edit the look of - by having a transparent texture that is on a big quad, scroll across the screen (transform position changing) and you just create a gradient or whatever to have it appear to do this wipe thing. Then might as well have it flip 180 degrees once it covers the screen to put the “fadey” end on the other side, and scroll it further once the camera has moved or scene loaded… Not elegant but effective and easy! Good luck!
