I was trying to figure out how to make more 3D tiles. Like buildings and such. What i have come up with is making a 3D building using a 3D editor like Google sechup, Blinder,Truespace,& so on… When doen taking screen shots of them, then scale them down to fit the map size. Then i think you would have to go in and fix some basic things. I'm gana try this but thought id share my idea. ill post my attempts :)
