I'm working on a castle like building at the moment.. I call it MediEvalJail or Palais de Justice. Ok, a bit scary but have look. Some day it shall be Poser freestuff ... may be 1-2 months.

If could need it. The mesh is done, ok, in C4D, but can output as OBJ quickly. It's roughly assembled with material groups but not uv mapped at the moment. But procedural materials should work well but you have to do them in Vue.

It's round 60 MB, but I can split it as 2-4 parts for partial loading.
Have a look to some screen shots.
