As always all textures are baked before import, only ambient lighting is used.
Well.lol, I do a little research on everything I do, I dont go completely overboard and use a lot of license, the Inn doesnt have the arched roof common to medieval design, most of which gives a nod to Roman architecture. The beams are exactly as my friends house in Cricklade in the Cotswolds. I get a lot of ideas from tv and film set designs a nod in the direction of Blackadder here lol, other games such as Oblivion and of course google is your friend. Used to work for theatres,museums and galleries, so done a lot of set design and installations, one of my faves was full scale representation of a ruined St Kilda cottage, the professor I worked with had knowledge of how to create fake stone using polystyrene, plaster, glue and sand mix which looks like the real thing once painted, every detail was in there right down to the bird crap, I have created many fake stone fireplaces for friends since then, I love old stuff.
It was common to use an old wagon wheel with candles stuck on it as a chandelier, some more wealthy sorts would have an iron one, the fireplace is also common to the period.
