Hi Matadem, if that's not sub-d then I would not recommend trying to bring it into MOI.

Your model data will be made up of a lot of little planar fragments.

If you then apply exact booleans your result will be a weird mix of a faceted main body and smooth only on the cuts you apply in MOI.

The main way that it could work would be if you constructed the body as a sub-d model in your poly modeling program. Then the main body would be a smooth surface in MoI after you convert it from sub-d.
