My map is done, so I export and rename the file into a .bsp, then I put it into the tf maps folder. When I try to load the map it does not work, please help.
"Rename into bsp"? No, no no. What you need to do, at minimum, is to use vbsp to compile the map. Hammer comes with a built in option to run it for you. Press the run button (shortcut F9).
