I’m new to Unity. In my game I would like to render everything to textures. I then want to map those textures to quads and render to screen only those quads. Lets say I have something ready to render, like a mesh or canvas. I need to set certain camera as rendering output for that mesh/canvas. How can I do that?
One way to do it :
- Set your objects to layers
- Set the culling mask parameter to your camera with the layers you want to render with this camera
- Create render texture assets
- Set your render texture where you want to write in into the renderTexture parameter of your camera
- then this render texture is usable as a normal texture so you can put in into a plane or use is with any material as a common texture

Lets say that I divide my screen into four rectangles. Each rectangle is one camera viewport. How do I control what is drawn where? I understand that I need to apply transforms into camera space, but I also need to apply them to a particular camera space.
Are layers the only way to assign something to a particular camera?
I guess if you explained what you wants to achieve it would be easier…
