Render To Texture Information

Hello Unity,

I am currently working with a very small development team on a game that we are looking to announce at Develop Conference in July.

Part of our game requires a map overlay of our procedurally generated levels and we are looking to do this using render to texture. In order to get this working in the way we need, we ideally need to use a render texture to store image and depth data from a camera and then use that information to render into the scene. Unity seems to have a cameradepthtexture macro but unfortunately we have not been able to get the data out f it that we need.

Is there another way to access this information?

Thank you.
