After 2 days of experimenting I found best way for worfkflow MOI and 3D coat.
Export from MOI High Poly with Ngons. It's not necessary have to be very High poly just enough polygons to trunsmit smooth geometry, 12 is a good number.
After that imoprt it to 3D coat, and make retopology, 3D coat has good tools for this. Or you can export from MOI Low Poly (has some issues).
