Unfortunately, using such a total cloning method will put higher demands on computer resources and may eventually oveload some systems.

The SH3 engines smartly allows for multiple use of 3D meshes. It is only the object "representation/description" needs to have an unique ID, not the 3D mesh itself. That allows for lower memory consumption without loading multiple copies of identical 3D meshes. Therefore, it is enough to change only IDs given by DAT navigator plus TGA IDs to get a fully functional clone-model in the game. The 3D mesh needs to have the unique ID only when it is to be edited/modified.
