It really is too bad you are having trouble with you latest map, it would definateley be the best out of every map you have ever created before, I wish I could help with your mapping problems
Those vehicles look really cool and they would really enhance your game play. I personally would very much enjoy flying around in one of them for hours on end.
I really wish I could help, it would be awesome to see those models in action. I hope you can find a good animations person Vegeta, your map will be so much better with them.
