<description>
Specifies the smooth group to use for the [i]next[/i] vertex. If this is never called, all vertices will have the default smooth group of [code]0[/code] and will be smoothed with adjacent vertices of the same group. To produce a mesh with flat normals, set the smooth group to [code]-1[/code].
+ [b]Note:[/b] This function actually takes an [code]uint32_t[/code], so C# users should use [code]uint32.MaxValue[/code] instead of [code]-1[/code] to produce a mesh with flat normals.
