no have no idea.....i have pics of my map, huge map, but:
no spawn point, nor textures so all i can do is spectate for about 30 sec.,and see like a checkerboard affect. i dunno anything about it. but i do know this, i have no textures, and no entities (lights, spawns, etc.) so hell.....i'm S.O.L. Sh** Out of Luck.
lol use the gtk radient it much more easier u dont need to go extracting anything u just open program all textures rdy and all much better
