Jetamo(Jethro) here, long time TF2 player, first time mapper. I've dabbled in Hammer once or twice, but not really making anything(a block room. xp) I was wondering how hard it would be to make a one-stage Payload Race? Standard stuff, maybe an alpine setting. Anywhere I should start, etc? EDIT: Also..say I properly make the map and stuff, is it easy to replace the cart with something else(if I get a model)?
