THE LOG SAYS LIKE THIS…
UATHelper: Packaging (Windows): LogCook: Error: GameDefaultMap contains redirected reference ‘/Game/VRTemplate/Maps/VRTemplateMap’|hpp. Those assets will not be loaded in the package build. To fix this, reselect the asset in the project settings.
EVEN THOUGH THE PACKAGING IS DONE, THERE IS NOTHING IN THE SELECTED FILE.
Hello yoona1219 and welcome to the Unreal Community.
From the error itself it seems the solution is there. “To fix this, reselect the asset in the project settings.” I would check the project settings where you have your maps selected and ensure it is set properly.
On another note:
Before packaging again, please ensure you have fixed up redirectors to clean any lingering redirectors if anything was renamed or moved during your development.
I hope this information was able to help you.
Open your project settings and go to maps and modes and under default maps set your editor startup map and Game Default Map. This should fix the issue.
