I tried putting the map in the maps folder created by BSP. I'm able to compile and test it using Quake 2, but it doesn't show up on the map list for creating a LAN server.
Is it possible to extract the EXUX textures from the .pak folders? Jitspoe told me that it is not OK to distribute them, but since I have a legitimate, physical copy and have the textures on my computer, I would assume it would be OK to extract them and use them in Paintball 2 jump maps because I hate the annoying, grey grid.
