Hello! I am trying to project the view of a camera onto a 3d plane like a texture. I am currently working on a game and I want to add a security camera. The player should be able to see everything the camera sees on a computer display. Is that possible? Thanks in advance!

Have you looked into using a Viewport as a texture?
