fade between scenes?

I don’t mean fade to black and then to the next scene. I’m talking more about scene masking. Is it possible to layer scenes based on an alpha of a guy texture?

You may want to use render to texture on this.

Make a render to texture image about the same size of your game resolution and make your first camera render to it.

You now may use this image as GUITexture, changing the alpha you’ll get your transition.
To use an alpha mask in this, I think that you’ll need to change the Clear Flags of the first camera.

Hope it helps.
