Minimap Camera Question

In Unity 4.0 Free, Can you make a camera look rounded using a transparent texture?

What I mean is, can you take any given camera and make it view in a rounded effect? I know its probably hard to understand, I dont quite know how to explain it.

The default camera view is in a rectangle shape. Can you make the camera view in a circle shape, and make the area around the circle transparent? Perhaps using a texture mask or something?

Hm, maybe have a look at this: Unity - Manual: Render Texture You could make a shader with a round mask and get the texture, the camera produces at runtime. But I think the performance would suffer and you just make a square minimap :slight_smile:
