I am not sure which approach to chose for sculpting a character and afterwards conversion to polysurface in Rhino. I will be sculpting a character in a Mudbox, usually I do these sculpts for 3D printing, so I just export them straight from Mudbox, but this time client wants to convert it to NURBS so he could use it in CAD software.
My issue is that I am not certain what is the best way to create all of the elements that make the model. What I mean is that character is wearing a vest and shorts. In a standard case I would make them as separate parts (which do intersect), so for example my model would be made from separate meshes for vest, shorts, belt, maybe hair, etc.
My question is: Is it still acceptable approach to model all these elements as separate objects and then to BooleanUnion them once they are converted to polysurfaces? Or should I try to keep number of separate objects to a minimum?
To point out: I will be retopologizing my sculpt to reduce polycount but to keep required details in.
