Not exactly. RT used Poser and maya (i think now just Maya) for their model creation. In Poser at the very least, certain clothing items (shoes, headwear, etc) are a seperate model which the main character model 'wears'

In the case of Pyrrha's tiara thing, it is likely a seperate model attached in this manner; meaning no second version would need to be created.
