Packaging Advice

Hi all,

Got a packing failed message. Looking at the log it’s because it’s trying to package levels that are not complete. I want to package and share a few complete levels only for some friend reviews and testing.The packaging process is picking up EVERYTHING in the project. So how do I exclude the elements that are not required to avoid getting the errors and failure?
Doing this manually by copying the whole project, removing content I don’t want then packaging seems very inefficient!
