[3ds Max] Python SDK - Skinning data

Accessing skin modifier data via Maxscript is slow so I thought I’d try getting it via the Python SDK.

We have it working fine via the C++ SDK in an export plugin but I can’t seem to work out the interface ID to pass the GetInterface function in Python.

C++:
ISkin *skin = (ISkin *)mod->GetInterface(I_SKIN);

Python:
skin = mod.GetInterface( ? )

I’m assuming that ? should be an interface object, but I can’t seem to find the value for it.

Anybody have any idea?
