Good luck with it - I hope someone can help you, especially as to this modding noob it does sound like it should be fairly simple.

Umm, while I have your attention, could I possibly ask a completely unrelated question? Are there are Maxis picture meshes that have suitably medieval frames? I'm making a few recolours at present, and some of the textures are distinctly medieval looking, so I wanted to use an appropriate mesh if possible...
