Power armor rigging problem.

[MartinusHUN]

Hello everyone!

I'm having problem with rigging my new power armor what I'm working on. The meshes are done, and works fine (shows in game) without rigged (boned). But if I copy the bones/helpers from another power armors file, the game crashes. I tried nearly everything and watched a lot of tutorial videos on youtube about model rigging without any luck.
I cannot test the armor unrigged.

I know how to put custom meshes into the game (I have a working test melee weapon.)

I'd appreciate very much for the help if anyone could tell to me or show to me how this magic works.
I'd appreciate very much for advices too.
I have 3ds max (and blender, but I cannot import/export rigged models with it).
Thank you for the help and for the advices.
