Are You Sure Your Path Is Correct?
Seems to be missing a '\' there. Also put the path between double quotes.
There should really be no problems at all with that. If all fails add the QBSP.exe path to your PATH environment variable and try to reset cmd and use QBSP directly.
Do you have any problems running qbsp.exe directly from the maps folder? You'd either need a batch file or open a Command window there to add the -map mapname part.
Try moving everything to be in paths without spaces e.g. c:\quake
Yeah it's pretty clearly choking on the spaces.
The time-honored way to deal with this is to use paths without spaces like ericw says above.
If for some reason you can't do that, the other thing that might work is to use DOS-style paths, like using "PROGRA~2" instead of "Program Files (x86)".
THANK YOU!! :D
It works! I simply had to copy all of my Quake files over from the Steamapps folder to C:/ (I have to type forwards slash otherwise the forum removes the backslash) and then reconfigure the filepaths!
Thanks so much! I can't wait to get into Quake mapping!
