Render the camera with shader replacement.
See Rendering with Replaced Shaders page for details.
This will render the camera. It will use the camera's clear flags, target texture and all other settings.
The camera will not send OnPreCull, OnPreRender or OnPostRender to attached scripts. Image filters will not be rendered either.
This is used for special effects, e.g. rendering screenspace normal buffer of the whole scene, heat vision and so on. To make use of this feature, usually you create a camera and disable it. Then call RenderWithShader on it.
