If you did the old GeoPcDx can be copied across and repaints on the old model will still work.
"the class 47, 166 and SD40 have been remade and remapped.
How will that effect your old ones? they should function the same, however, new people who try and copy the geo file and apply the old skin will find that it will not work.
So, my advice for folks who want to keep old skins is to keep a back up of those files mentioned as they are now.
I don't think RS.com will have anything against folks adding the (RS2) geo files for those 3 core locos into the reskins.
