List of layer masks to use with Physics.Raycast()?

[bonesbro]

I've been trying to find documentation on the layer masks that KSP uses and haven't been able to find much. Does anyone know where a list of the different masks?

For example, KethaneExtractor uses bit 15. KAS uses 1, 2, 15, and 19 when looking for parts (557059, 0x88003). Something else switches off layers 2, 11, and 13 (which is 0x1402) and calls them the "DestructionCollider, ScreenSafeUI and ScaledSpace layers".

Derp. An actual list of these layers would be nice

There's no list as far as I know. The most widely known is 1<<15 to check altitude from surface. If you want to do something else, you'll probably have to go with try and error.

[a.g.]

Use this to find out what the bits mean:

for (int i = 0; i < 32; i++)

Debug.Log(i+": "+

LayerMask.LayerToName

(i));

For future reference, that returns:

To add to that list, Parts that are part of the current vessel are on layer 0.

I had assumed that all parts being rendered were on layer 0, but the layer 19 being labeled "Disconnected Parts" makes me wonder. All my tests involved the current active vessel, I never had a reason to check the layer of parts not attached.
