As I saw
Zachary_Gray wrote earlier. In Photomode, with no mods in the game at all since the 1.6 patch I can not move the camera i.e. point it anywhere. nothing happens when I try to hold left or right mouse button to change the viewpoint. the mouse wheel can zoom in or out. The pointer also works moving around in photomode. The mouse look works fine outside of photomode.
I have tried recreating the UserSettings.json file but that wasn't it.
Edit: after some file checking and moving files into backup folders. It seems like the updated:
"inputContexts.xml"
"inputUserMappings.xml"
doesn't get transferred to the cache folder. I tried moving the files out of the cache and the game crashed. I then made a repair and it recreated:
"final.redscripts"
"tweakdb.bin"
but it did not restore the xml files above. so when copied from r6\config to the cache it worked and mouse movement in photomode worked again.
