Render the camera manually.

This will render the camera. It will use the camera's clear flags, target texture and all other settings.

The camera will send OnPreCull, OnPreRender & OnPostRender to any scripts attached, and render any eventual image filters.

This is used for taking precise control of render order. To make use of this feature, create a camera and disable it. Then call Render on it.

You are not able to call the Render function from a camera that is currently rendering. If you wish to do this create a copy of the camera, and make it match the original one using CopyFrom.
