Can you edit the preset layers?

Unity Engine

I am making a 2D game where the main layer is orthographic, then 3D backdrops and “foredrops”, and also
a background. Further more, there are 19 different active cameras which use different layers. I have just reached the limit of 31 layers, but I only need 2 more. I see that that there are built in layers that are empty, so are there any ways of editing these? I do not plan on adding more layers or using other people assets that would add more layers.

Also, is there a way to render an object on only one specific camera without having to create a whole new layer?
I have a lot of single objects that are only on one of the cameras. Another question: Is there a way to depthmask a camera without giving it a layer? I don’t feel I am overdoing it with the cameras, since it is one of the main mechanics of the game, and it runs smoothly.

Depends on what you are doing with the cameras. You don’t actually need different layers for them if they can’t see stuff they don’t need to. For example, we many cameras, but we just position them and there content out of view and range of the other cameras. If your backdrops don’t actually interact with anything place them way out of range, they won’t need another camera then.

I am curious why the single objects need their own cameras? Visual fx? I don’t believe that depth mask is dependent on layers. As I said we use many cameras, and only use a couple of key layers.

The built-in layers can’t be edited, no.
