I am going to close this without changes because they are not needed. The API already supports all scenarios. When NoesisGUI is being rendered to a main camera, as explained in the documentation, 'NeedsRendering' must be used with a manually repainted camera. Manually repainted cameras must be disabled (the Camera component, not the gameobject) and Render must be invoked when needed, for example attaching the following component:

public class Redraw : MonoBehaviour

{

void Update()

{

NoesisView view = gameObject.GetComponent<NoesisView>();

Camera camera = gameObject.GetComponent<Camera>();

    if (view.NeedsRendering)
    {
        camera.Render();
    }
}
}
