Hey there,
If you are on Windows 64 bits, do the following to fix the issue:

Go to your UnrealEngine folder then Engine>Build>BatchFiles

then open cmd there and type the following command:

Build.bat UnrealLightmass Win64 Development -verbose

and wait then try again, it worked for me :slight_smile:
