Hi! I'm DryreL.

I’ve prepared a .bat script file to help you build.

Simply right-click the .bat file, select Edit, and manually enter the UE path and uproject name.

If you receive an error during the build, the command prompt will wait before closing so you can read the error.

1) EDIT THE FOLLOWING VALUES:

2) BAT LOCATION

Make sure to put this .bat file into your {ProjectDirectory}/Build folder.
