    I need to duplicate cameras and objects.

    Each duplicated object needs to be seen only by its respective duplicated camera.

    I could do this if I could create new layers through script and set them on the new duplicated camera culling mask.

    However it seems layers cant be created during runtime.

    How to solve this? Lets assume a situation where I instantiate 1000 cameras and each camera looks at their respective 1 out of 1000 objects.

    No need to raise concerns of performance, just wanted to know if possible or not, thanks!

    Not as you describe it here no, but if I follow you, you could have 1000 additive scenes each with its own camera and just share the layers (keep them the same). Each camera would need to be instructed to only render a specific scene by using: https://docs.unity3d.com/ScriptReference/Camera-scene.html

    I can honestly say that I've not thought long and hard about what I just said so may have terrible flaws. ;)

    Put them in 1000 different places (in space) and set the view frustums up so they're small enough they don't interfere. See below.

    Multi-camera multi-layer (and even multi-light) stuff is for things that are all colocated, such as using it to get ground cursor highlights on an RTS game by using multiple layers.
