[Closed] [3ds max] [maxscript] script to export/import explicit normals

hello!

I need a script to save and then load explicit normals for selected objects. so the process is like this:

1. select object
2. press button to export normals into a file. normals saved along with object name
3. deselect/object again
4. press a button to read saved file. script sees the name in the file and if this name equal to selected object’s name then it creates Normals_Edit modifier and loads explicit normals into it

p.s.: in 3ds max (2009 precisely) skin modifier recalculates the normals.
