"This will copy the normals from a master object and apply to various target objects - based on vertex distance between them.
For each vertex in target object - the script will search the closer vertex in master object. Then will copy the normal of this vertice to the target. You may try the extra option for more precise normal placement - but the default works fine. If the master or target objects have a lot of vertices - the process may be slow. When running - max usually don't refresh the views and everything become white... this is normal - just wait and it will finish well !"
