Missing materials in packed project

I use UE 4.8.2 (also in 4.8.1).
When I pack project- win64/shipping most of the materials are missing ? replaced with gray checkerboard…
In editor and preview play everything is fine.
What I’m missing?


-Make sure that you have saved all your assets in your content folder.
-open the log while you package your game and check if you can find some errors/warnings :slight_smile:
