Weighted Vertex Normals

[+GKABS]

This MaxScript generates Weighted Vertex Normals for any arbitrary geometry.

It should be compatible with 3DSMAX 9 and up. No dependencies on this script are added to scene files, so your scenes can be shared with users who don't have this script installed without issues.

'Weighting' of vertex normals means that each face normal contribution is scaled by a property of the triangle. This script uses the triangle surface area and corner angle as influences. The result of this is that a small triangle will have less influence on the shading of its larger neighbor. Likewise, the neighbor will have a larger influence on the shading of the smaller neighbor.
