How picky is the KSP engine with regards to single parts and the meshes that they are composed of? Am I able to overlap multiple, but independent, meshes under a single part or will that throw an error? I understand that KSP requires that each ship component be 1 'object' but that does not, necessarily, mean that that one object cant be composed of multiple meshes. For example, I\'m modeling a fuel tank and would like to add some detail features. In particular I am aiming to model a small hose that runs down the side of the tank. Can they be individual meshes or must they all meet at common verts at some point?
