I made a low and hig poly asset of this Walnut, after the scan, i used zBrush for cleaning data and zApp-Link for cleaning texture color. Then Topogun for retopology and knald/xNormal and photoshop for the maps. I did it during the course Photogrammetry for Games with Jonathan Rush! Awesome Course!!
Low Poly:
Open Walnut: 558 tris
Closed Walnut: 628 Tris
