I have mapped a button in settings to take screenshot but nothing happens. Am I missing a step or what? It used to work just fine!
might be the screen shot folder was moved. Look in Steam, or the rF2/User Data or....inside the Documents folder. Also check the Assign menu section to verify your key is still assigned.
When did it work for you the last Time? And you talk about the rF2 Screenshot, not the Steam Screenshot, right? There is a Bug since a longer While, where the Screenshot works only, when you are on the Track, but not in any Menu or the Showroom. (I'm on the default Build, not the release Candidate.)
My screenshots got moved to: steam>userdata>130142731>760>remote>365960>screenshots. Hope this helps.
rF2 is using the Seam screenshots system for some time. Check your Steam screenshots folder to be sure.
