The camera and cctv monitors are my own models, applying an image the the screen isnt a problem, and I already have camera objects parented to the cameras. What I was hoping for, is a way to render the view of each camera and assign that to an input in the materials room, like where you have the option for an image, or video file, have an option for 'Render from Camera X' or something like that. Done 100% in program, I dont want to render CCTVCAM_A, B, C, D, E, F, G and H individually, then apply all of those images to my monitors. What if I wanted to produce an animated clip with physics? each shot could end up looking different if they're not all rendered in the same single pass.
