Part of ArmA2-ArmA3 project building ships for use in ArmA3
Method in ArmA2 was to have a bigship vessel, with the the visual hull parts including roadways and geometry attached under 'attachTo'
This allowed the restrictions of 50m lengths to be overcome in total although each section was within the 50m limits.
InArmA2 the roadway and geometry worked.
However in ArmA3 these do not work under attachTo when dealing with other vehicles, but do work when not attached. (as in trying to drive on them or collision detection_
I have tried many different parts, they all have the same affect
