whats wrong with bikini? i had so much trouble with that one,i went over it for 2 weeks before i released it,and i'm laying off the lighting,i've learned a few new tricks and really going over the maps trying to check every angle and every building.
what impractical collision are you talking about,i try to avoid these as much as possillble i also try to keep the brush count down.
and interiors are what the maps are all about for me,anyone can map a map without one,but they make the game IMO,look how many people play bedroom.
belive it or not some people have complaing that theres not enough textures on some maps so that looks like a no-win problem
i am working on 2 maps right now,an airport map and a midevil castle type map,and i am puttting hidden places in the maps, some only admins can access, and some for everybody.
