Graphics

I'm doing a few things in 3D, but would like to be able to have some static overlays on the screen. The 3D is using a perspective camera; the 2D/overlay stuff would use the standard default camera.

I realize I can make a full screen quad and apply a render view texture onto it (and then I'd just be using the default camera), but I was hoping there was more of a built in way, like telling the a layer to use an independent camera. I'm experimenting with a cameralayer, but it doesn't seem to work.

Why not just put create your 2D/Overlay in a different scene and play it out on a different layer (on top of the 3D conent)?

EDITED: The bottom line is I'm just trying to find the simplest solutions - there will already be a lot of scenes. But I think it's a good answer.
