VertexNormal:Void surface:Int32, index:Int32, nx:Float32, ny:Float32, nz:Float32

Parameter	Mode	Type	Default	Description
surface	In	Int32	required	Surface handle.
index	In	Int32	required	Index of the vertex, from 0.
nx	In	Float32	required	X part of the normal.
ny	In	Float32	required	Y part of the normal.
nz	In	Float32	required	Z part of the normal.

Description

Sets the normal of a vertex: the direction it faces, which decides how light hits it. The normal should have a length of 1. Set it yourself for hard control over shading, for example to make a flat quad look rounded. UpdateNormals overwrites all normals of a mesh.
