Looks like a lighting difference between this and the finished version in the game. May I ask what you changed?
got here from OpenGameArt - nice work
Fits perfectly. I've tryed a time ago do something like this on 3DSmax. After the cameras kicked my ass a lot ( pricipally on floor tiles ), I gave up.
Seeing them put together like this gives it a whole new level of awesomeness . Great work!
