The project that I’m working on recently upgraded from UE5.2 to UE5.3. After the upgrade, I and one other team member have been affected by an issue with the project that is seriously slowing us down: when we try to build the editor or the project itself in Visual Studio (via right clicking on the project and selecting “Build”), it triggers a full rebuild of the project, no matter how small the change was. None of our other engineers are experiencing this.
Additionally, when I go to open the engine binary that this build has produced, I receive the dialogue, “The following engine modules are missing. Would you like to rebuild them? [Projectname] [ProjectnameEditor]” every second time. That is, I can open the engine once, then on a subsequent run I’ll receive that message, then after I hit “no” I can try to open the engine again and it will work, then next time I’ll get the message, and so on.
At this point I’ve tried:
- Cleaning the UGS workspace
- Cleaning the solution and individual projects within Visual Studio
- Swapping from VS2019 (which we’re all using) to VS2022 (as it’s the recommended version for 5.3)
- Ensuring that I’m on the same minor VS version as the teammates who are unaffected
- Completely deleting my project directory to ensure no intermediate files persist, then fetching the project from source control again
- Deleting the Visual Studio cache files from AppData in case there are some bad intermediates in there
Of course each of these steps requires that I fully rebuild after before making some minor change to see if that will trigger another full rebuild, so it’s eating up a great deal of time that we haven’t really got.
I suspect there have GOT to be some temporary files somewhere causing this, but I’m at a loss as to where at this point. Has anyone seen anything like this?
