scrolling/animated light cookies

is it possible to make these? and how so? I’m trying to create cloud shadows for my terrain, like the kind you see in STALKER or far cry 2

Hi, welcome to the forum!

The light cookie is of type Texture rather than Texture2D so it should also accept a MovieTexture. However, MovieTextures are only available in Unity Pro. You may be able to get a similar effect by cycling through a set of static textures. With either method, the most difficult part might well be creating a realistic moving cloud image to begin with.
