I’m wondering if/how one could render a scene in Unity which (as this is the best way I could describe it) would render the game out like a modern port of an old game. I’m not talking about the TV filters (although as I mention that I am suddenly a bit curious) but how the image is rendered in two parts.
- There is a background “wallpaper” image that fills the whole screen.
- There is a window that shows the actual game, but it DOES NOT fill the whole screen.
I thought about the idea of just drawing a border around the portion of the screen I want to be “wallpaper,” but that really would not work out right in the end; it would get screwed up depending on the rendered resolution and would be difficult to maintain the camera correctly.
I recall when I first was learning Unity I saw something that said you can have multiple cameras in a scene and then layer what those cameras render on top of each other. Is there a way to set it up so I can have what is rendered not fill the entire screen, but only fill a desired resolution?
Furthermore, I wonder if there is a way I can set up one of those cameras to render to a specific set resolution, and then have that rendered image drawn on the screen (and scaled if necessary)?
