Hello everyone ! i was trying to create an archviz scene for realtime walkthrough but the the problem is failed to create package. it says Missing UE4Game binary. You may have to build the UE4 project with your IDE. Alternatively, build using UnrealBuildTool with the commandline: UE4Game [3811…

I had the same problem after loading the engine from github. Solve it very easy. Adding code to your a pure blueprint project (File->Add Code to Project->None). It allows to be packaged from the menu.
