    I was wondering if anyone has an easy method to do some fake lighting in Unity.

    With other engines, I accomplished this by drawing a dark surface over top of all layers (minus GUI) then subtracting the "lights" by subtracting the alpha channel. It was quick and dirty but I haven't really seen anyone really doing this with Unity.

    I know the idea behind it is simple but I can't really can't find anything in the API reference about creating seperate draw surfaces like GameMaker for example.

    Ideas, Comments welcome

    Just chatted about this earlier.
    Thanks to @Aedous for explaining the technique.

    Let me know how you get a long, I'm not good with shaders at all, and my method only gives you a specific type of light :). However since it's a sprite I guess your light can be any shape.
