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

I don't understand why this happens. And does it only affect the hands and face? Does nothing disappear in the game itself?

No, the model is corrupted during import. I extract it from Heroes, and it turns out like this, so it will be like this everywhere.

I think we need to optimize the face and hands in Polygon Cruncher to reduce the polygon density.
