Normal generation options for ModelImporter.

Normals can be calculated by Unity using several methods. They can be either unweighted or weighted by area, angle or both.

See Also: ModelImporter.normalImportMode.


Unweighted_LegacyThe normals are unweighted. This option uses the legacy algorithm for handling hard edges.
UnweightedThe normals are not weighted.
AreaWeightedThe normals are weighted by the face area.
AngleWeightedThe normals are weighted by the vertex angle on each face.
AreaAndAngleWeightedThe normals are weighted by both the face area and the vertex angle on each face.
