UDK Static meshes, LODs, blocking volumes, light importance volumes, multiple UV sets, tiling, procedural materials, Kismet etc. Then you hit Unreal scripting. Which platform are you targeting?
AI is kind of funny. X)) If it's programmed to pick the best way to achieve a goal, it would probably pick the teleport if it would help them reach their goal.I tried putting a health vial behind the portal and that works great. So I'm guessing a teleport device is not an object of importance to bots. The bots would open the turbolift doors and see a teleport and say "oh, it's just a stupid teleport, no thanks". That seems kinda odd to me.
