Green_Shade: Any idea where, if anywhere the in-game (not Galaxy) screenshots are getting saved? They're not in any of the ordinary places I looked, nor where the INI file implied they would be.
MathPhysicsNerd: Have you checked under the games' location in the GOG Games folder? There might be a special section for it there
Yep, that's where the INI file implied they'd be under A Hat in Time\HatinTimeGame\ScreenShots but no dice. I even tried making the folder to see if it would help. Before the question comes up, this is on a separate drive without UAC issues. And the paths in the INI file are relative, not absolute. So unless the game doesn't recognise relative paths... Thanks for the answer too.
mmodri: From looking around various sources, I conclude that this is probably a bug in the GOG version as I saw no other place mentioning anything about photo mode or where the files end up (except 1 post on steam forums regarding this from a GOG user). I'm assuming the game uses Steams built in screenshot function when you take a photo, hence it does nothing on the GOG version.
I think you're right about it being a bug, but I don't personally think it's Steam-related. Of course I can't prove that, but them having a specific INI path for screenshots kind of points that way.
