转载地址Scene Background

You should create 2 cameras. Name the first one "Main camera", name the second one "Background camera".

1. Create a GUI texture (Gameobject->create other->GUITextture), drag your picture from Project to Texture in Inspector panel. Create a new layer (example: star) and assign it to that GUI texture.
2. Choose Background camera in Hierarchy. In Inspector panel, set Clear flags to Solid color, Culling Mask -> Nothing and then Culling Mask -> Star (layer)
3. Change depth to -1.
4. Choose Main camera.
5. Set Clear flags to Depth only.
6. Culling Mask -> Uncheck "star" layer.
7. Change Depth to 1.

Remember to remove Audio listener from the background camera
