"flat: forces one normal per flat part.
object: does not produce standard normals, but leaves the object-specific ones untouched.
sphere: forces normals to behave as the object would be a sphere."
Suggest with some questions:
"flat: one normal per flat part.
object: apply object-specific normals (I am assuming these are specified using other dr3d attributes on objects?)
sphere: normals behave as if an object is a sphere.
