Lol it is probably a misunderstood on how to cook only the assets used in levels (“Directories to never cook”).
Where can i find a simple tutorial on that without having to includes every folders in cooking ?
Here is a feedback useful if you have the same issues:
After restarting from a blank project,
I added step by step each dependency and plugin and after packaging the game each time one dependency after one dependency,
i found that some plugin like “Json to Struct and Json or Csv to datatable” canno’t be used into a Blueprint Actor component for the character player or you will get the packaging failed.
I had to move my blueprint nodes into the blueprint level map to get a successful packaging …
in resume : NEVER WAIT THE END OF THE GAME DEVELOPMENT TO START A PACKAGING !!!
