Hi Kenmo, that's basically a limitation of 3D Coat - other programs like Modo, Cinema4D, are able to work fine with UV mapping on N-gon meshes and do not require only all quad sub-d type mesh structure to do those tasks.

If you're not going to be applying any displacement at all then probably 3D Coat is not the best tool to use, at least in combination with MoI.

If you need all quad edge loop topology as your output then you would generally be better of creating your model in a sub-d modeling program from the start rather than creating it in a CAD program and trying to automatically generate all quad sub-d edge loop type geometry from a non-edge-loop based source model.
