I have upagrade me project on UE 4.10, now at compile i have Map Check Errors “[ObjectName] : Externally referenced” for fiew objects.
I read doc but no way…


This always happens when you upgrade a project. Try the following. Close your project. Rename project folder (just add any letter). Open this project again. Usually after this, Warnings in Map Check disappear. Close project and rename project folder to original name.

Tank you, problem Solved !

What if they don’t disappear? They stay anyway.
