I am attempting to use the Common UI plugin in a 5.5.4 project. I’ve done this before and had no issues. With my new project, I noticed that every time I would restart the project, the Game Viewport Client Class would be reset to DisplayClusterViewportClient. I tried to export my Project Settings, and even though the editor showed Export settings succeeded the settings were not saved.
I have checked the folder properties in Windows Explorer, and the project was set to partial read-only. I turned read-only off for the entire folder, and still the Project Settings refuse to save.
It’s like the Unreal Editor is refusing to save any project settings at all anywhere for any reason. Is there something I need to change at the project level? Is there some editor setting I’m missing? Is this a Windows or a git issue (yes, I’m using git for my scm)?
I had a strange issue where a keybind that I was setting was not being saved. (In Editor Preferences instead of Project settings, but maybe these problems are related)
I think what ended up solving it was instead of using the ‘Search’ field to navigate to the setting, I just found it manually by clicking on its category and scrolling to it.
Probably should have dug deeper at the time, but it could be something for you to try.
Disabling the nDisplay plugin was the only way I was able to get my Common UI settings to stick.
Caveat: disabling nDisplay causes other issues. I had to go in and manually comment out all references to nDisplay in the .ini files AND manually comment out the entirety of the Windows config ([project_root_folder]\Config\Windows\WindowsEngine.ini) before Unreal Editor would launch again.
