Thank you for reply. Looking forward to it!
I managed to make it work somehow, had to use "Converter -> Blender -> 3DMAX -> Blender -> Converter" killing combo each time, but it works

One thing i noticed is that the EXAMPLE file for weapons on wiki is not correct. The hierarchy there is not the same as in actuall weapons, exported from the game. It is very confusing when you try it for the 1st time.
