Set the normals of the Mesh.
See Also: normals property.
|start||Index of the first element to take from the input array.|
|length||Number of elements to take from the input array.|
|flags||Flags controlling the function behavior, see MeshUpdateFlags.|
Sets the vertex normals of the Mesh, using a part of the input array.
This method behaves as if you called SetNormals with an array that is a slice of the whole array, starting at
start index and being of a given
length. The resulting Mesh has
length amount of vertices.
