Is there a way to change the built-in layers in Unity?

Hi, just wondering if it is possible to change the built in layers in Unity?

The fact that some are blank makes me feel like I should be able to, and if so I want to take advantage of them.

Thanks!

The manual states “You can’t rename them but you can still use them.”. Most of these are for backwards compatibility.

Water and TransparentFX have such a fringe use-case, these should not conflict. Only Ignore Raycast and UI you shouldn’t use outside their intended purpose.
