Hi :)
I model in 3d (using Blender) and
have created content (mods) for a number of strategy games. More
prominently Civilization III, but also Medieval 2: Total War and Age of
Wonders mods.
I do this as a hobby, yet if anyone would be
interested in models or rendered gfx of my focused-upon architectural type
(intricate monuments, etc), you can contact me. They come with a small
fee, yet feel free to ask (as I noted, this is a hobby for me, not a
regular job :D ) RPG games may work just fine with medieval cathedrals.
Anyway... in the following render there are three of my Byzantine models: The Hagia Sophia, the holy apostles, and the Acheiropoietos. First one in Constantinople, the other two in Thessaloniki.
Regards, Kyriakos
