Packaged game look different from Standalone

Hey,
(sorry for my english)

The lighting looks very different in the “Standalone Game” and in my packaged version. 3 days ago i have no problem and now my shadow are too dark and my light to brigth. I delete my post process, change the auto exposure, exposure biais… nothing change. (left hand column in editor or standalone and right end column the package)

Does anyone know what makes this happen?
Thanks,
