Maya 8.5, I took a class in it last semester. I had some issues with the stairs, if you look at the original map, some of the stairs don't seem to occupy all 3 dimentions...(like they're painted onto the wall) So I had to take a little creative leeway... But I suppose a few things can't be helped... I plan on making the whole palace one file, continous mapped, from the main hall to all the corridors, to the rooms, to the mammon machine... if they all fit without overlapping.
(BTW, the mammon machine the JS rooms both use the same hallway right? and the Throne room uses a different one?
