Graphics.Blit(renderTexture, null) doesn't blit to screen unless main camera target texture is null
Graphics.Blit(renderTexture, null) doesn't blit to screen unless main camera target texture is null
Documentation says that blitting render texture to a null render target will blit it to screen:
http://docs.unity3d.com/ScriptReference/Graphics.Blit.html
However, if you set Camera.main.targetTexture to a renderTexture, and then blit that render texture to "null" render target, it will complain that "Scene is missing a fullscreen camera". A workaround is to set Camera.main.targetTexture to null before doing the blit.

Note that even the workaround has issues, because any image effects on the camera will then get rendered at the full screen resolution rather than the targetTexture resolution, even if you set targetTexture to the proper texture again after the Blit. (this is probably a separate bug, but it's worth noting here)
