What are the different layers used for in VRChat? What special properties of some specific layers should you know?

Below I've listed the currently used (+ reserved) layers and their use cases based on experimentation using my layer inspection tools.

My layer research is currently ongoing and information on this page may still be incomplete!

Any object set to 19-21: reserved2-4 will be forced to 0: Default on build (You can still manually force the layer during runtime)
