Quote from VoodooBensheewhine whine - hammer is shit. the workflow is shit, everything is shit - point!
don´t waste your time learning that, go step ahead and try sb2, ue3 or id-tech - we are in the age of realtime editor lighting, turbo compiling and better and faster uses of custom stuff - or lets call it: "what you see is what you get-editing". not that crap which source uses *maeh*
Well, I would if I was interested in building the best looking levels, but I'm more into gameplay stuff and not really a level artist, so I'd rather go with games that have more potential in that area (in my opinion).
