I just converted everything to STEAM and it seems to run ok. I export to .MAP, batch compile the map, go to STEAM/GAMES/Halflife and enter console, and type "map xxxxxxxx" to load a map. No problems. I started getting Bad surface extents errors, so I started looking for solutions. After ripping several sections of my map apart, I realized that it wasn't exporting anything to .MAP format. When I open the exported file, there is nothing on the grid. Any help here would be appreciated! Thanks in advance!
