i have made this map for a start i made the first room okay then added a corridoor and rotating door then when i added my second room i can't go into it i just falllllll! i made it by making a box, hollowing it out and then carving with the corridoor (its the easiest way for me for now) so why can't i get into my room?
if the texturing on the outside of the map is the SKY texture, re-texture it. The Player will fall if the sky texture is on the outside of the map.
