Is it possible to render something from a camera to a section of the screen, on top of the normal game rendering? Like a picture-in-picture effect, or otherwise creating a sub-window?
In the past I’ve seen options to render to a texture, but presents some problems. Most notably the rendered image had to be square; I would like to render a sub-screen with more direct control over the aspect ratio and resolution. Besides, rendering to a texture implies a physical object, when really I want to render to an arbitrary portion of the screen.
