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

Hmm, I don't remember the exact polygon limit, but I think it's usually around 11K polygons. Yes, it's better to hide the model under the clothing; otherwise, it will be like the Skyrim clothing replacements, where everything looks fine, but when the character lies on a bed, parts of the body stick out through the clothing...

Clothing like that of the dwarf-mages – a robe that goes down to the floor, with a cuirass on top, or, for example, black-grade mages wear leather armor, but a cuirass would be better.

I didn't think about the hairstyle. I need to find an icon first and then create the hairstyle, or create a model for the existing icons, but one has a woman in a helmet, and the other has a woman in a hood (and is probably bald like all duergar).
