3 easy steps to creating veteran objects in 3do Builder.
1. Select the object you want to make veteran.
2. Go to object/create object and give it a name. It will place the new object right below the object you want to edit, but don't edit the parent object.
3. Select the parent object, go to misc/copy piece. Select the new object, go to misc/paste object. Then you'll be able to edit the new object's faces and add vet textures.
