just bypass to this comment :biggrin: component modding is a lot more involved them being able to slap whatever ever together in 3D Studio Max, its not a component making program it is a 3D modeling program which can make 3D objects,
from my understanding after you export it you need to do more work for attachment points, etc (which can be a bit of a pain.. I have tried lol)
the easiest way to to learn GMF editing from the numerous tutorials around, find components close to what you want and mold them yourself, 2 of the KOK prizes were just molded from other components but they dont look it at first glance
