A Mudbox scene can be rendered to a texture using render targets (RenderTarget). A render target is an abstraction of an OpenGL renderbuffer object. For more information see the OpenGL documentation (http://www.opengl.org/documentation/).

A render target has numerous slots to which Texture objects can be attached using the method RenderTarget::Attach(). By attaching multiple textures to a render target, multiple-target rendering can be achieved.
