RTF is a global modification that replaces all towns in the game.

That's strange... I didn't have these problems with other models.

Well, the only thing is, I used to work with previous models in 3ds Max, and these ones I started in Blender, then exported to FBX, but then I opened them in 3ds Max and attached them to the skeleton in 3ds Max, and nothing extra was displayed there... I don't know, I guess

I can't port the entire Gnomess, only in separate pieces, the hands and feet are there, I just zoomed in on the face.

Wait, and also, you're saying that the group editor doesn't port groups, but what about the last screenshot you showed? Where is the zoomed-in face?
