From this free object by Hrabale (11 000 polys )
https://sketchfab.com/3d-models/bota-5a4be383a62c4237b0eadb82f1ec9f8a

With the Native SubD / Create (28 000 at the end) 3 minutes ...heavy to manipulate!


With quads before import (11 000 quads)
With the Native SubD / Create ... 10 seconds! 837 Nurbs faces!


With ImportOBJ by Max Smirnov ...2 minutes... 11 000 quads faces nurbs


Render the 2 methods exports from Moi


So seems we must export from the first heavy image and method if we want more precision of the original model ! :)
Or improve the method of quadrangulation inside the "third party Poly prog"!

Or have inside SUbD something for regulate the precision ?
