Questions & Answers

In my 3D game, I’ve many computer screens models in my 3D map.

I want to display 2D things on thoses screens, differents things for each screen, sometime texts, sometime moving 2D GameObjects, like if a 2D game is playing on the screen, sometime animated sprites.

I know I can achieve that using RenderTexture but I don’t know exactly how to manage my 2D views. Where should I place them?
I want to avoid confilct with my 3D scene, is there a way to hide them completly while keeping their camera RenderTexture?

This is just an idea, not tested. If the screen is flat, maybe you can add a quad as a child to the screen object and place it just in front of the screen and draw onto that as a texture?
