BSP Troubleshooting

Issues Opening BSP Files

GtkRadiant is Not Installed

You attempt to load your BSP file and get an error such as "%%os%% Can't Open The BSP File Extension". If this is the case, it's usually due to the fact that you do not have GtkRadiant for %%os%% installed on your computer. Because your operating system doesn't know what to do with this file, you won't be able to open it by double-clicking.

Tip: If you know of another program that can open your BSP file, you can try opening it by selecting the application from the programs listed.

Outdated GtkRadiant

Your Quake Engine Game Map File file is incompatible with GtkRadiant because you might have the wrong version installed. You will need to download a newer version of GtkRadiant if you don't have the right version. This problem is predominately due to having a Quake Engine Game Map File file version that was created by a newer version of GtkRadiant than what you have installed on your PC.

Tip: Investigate your BSP file by right-clicking and selecting "Properties" to find clues on what version you need.

Summary: Not having the right GtkRadiant version on your computer can cause problems opening BSP files.
