Quake 2 bsp file

Ive loaded all the data from a quake 2 bsp file and am looking to display it on the screen, but when i go to display it i get a few lines and thats it, im sure it has to do with the viewing volume/scale of the map, but how would i fix this? thanks

Hey man give us some details:If only some weird lines are drawn on the screen nearly everything could be wrong…
