I used subdivide in cinema 4D, but I think it's the same as Zbrush use.
I just started this theme because I need sometimes to make low-poly model from MOI models.
First I think I can export with low amount of polygons and then high poly but this not works good.

But now I think I solve problem.
I export from moi High poly and the use Zbrush, Z-remesher to make low poly.

Michael may be you will give some suggestions how to make low poly from MOI model?

As I can see I'm only person here that use MOI not for Cad models)) But for games stuff and Art)))
