The help files say that you can't use render texture with TextureOutput().

This would be a slow process, but you could try SaveRenderTexture(). Then load the saved texture as an image. Now you could use ImageOutput().
This should work if time isn't an issue, but I'm guessing you need something much faster. That's the only idea I have at the moment.
