Skull Chopper:
Created as 1) all precision CAD NURB surfaces and solids using Alias, Fusion, and Onshape.
2) Also converted, retopologized, or rebuilt as polygons. Optimized as both Blender and Maya file versions. See details below.
Keyshot can easily import huge NURBS or Polygon files. This version has the best of both and it imports all UV maps from Blender or Maya.



Blender and Maya files created with polygons (below)




Polygons are almost always QUAD. Sometimes it decreases the number of polygons if you use Triangle around circular openings. The advantage of All-Quads is that you or others can subdivided it to make it smoother or edit easier. Avoid N-Gons = more than 4 sided polygons.
