Thanks a lot Artur, I’ll test with _CastFrom and see if it’s faster!
It seems that MaxScript refs.dependents, will let me go the other way (Asking a influence, what is skinned to it, if anything). For my use case this might be way faster. Do any of you know, if there is an equivalent in the Python API (Asking what depends on an object, rather than what an object depends upon)?
B.t.w. I’d love any recommendations on Max API training material. I’m assuming it would be for either .Net or C++, I haven’t found any Python Training as of yet
