Hi phantom,
this is an interesting observation indeed!
This would mean that the different .OBJ you were using are sharing equally structured groups.
It might also work if one .OBJ has more groups than the other, but I am not really sure.

I think the load process would crash if it would fell over groups that have the same name but different structure, because unequal structures are not expected in the code.

Did you use the loader itself or the morph copy program that comes with it?

I'm glad the tool helped!!
