Are you using the steam version?
If so, go to “Steam” (top left menu) then ”In Game”
You should see what screenshot shortcut key you have assigned and can also specify the screenshot folder.
Yes, I have the Steam version. You forgot to say Select Settings. Thank you, FX2K, but it still won’t work for some reason. Does the game need to be installed in the Steam folder on the C: drive to work? I have TF installed on my F: drive. Could that be why it won’t work? I might have to contact Steam to find out if you don’t know. Either way, thank you…
Also, do I need to Enable the Steam Overlay for it to work? I tried it but it still doesn’t work.
