Mirrored mesh vertex normal fix.
NOTE : If you do not have a good tool to make a perfect vertex normals look here: https://gumroad.com/l/VertexNormalToolkit
Script which can mirror selected meshes and keeps all normal information not distorted.
Supports edit and editable poly.
Does not collapse modifier stack.
ver. 1.5 supports hard edges. previous versions could transfer vertex normals 1 per vertex. Now it can transfer all of them.
ver. 1.3 has different method for aligning vertex normals.
It takes a bit more time but from what it was tested gives "true" correct result.
"True" - as it is the same as game engines "read" them.
ver. 1.1 is able to mirror any geometry in any combination.
Even simple primitive shape can be mirrored.
Works with any max version 2012+
For earlier versions it was not tested, however it is made to be used in previous max versions ( before 2016 )
