Levels Panel: What are the little blue dots?

Hello,

I work a lot with the Levels panel and some of my levels have a small blue dot just before there name. Someone knows what this dot means?

When looking into the documentation I just realized that the Levels panel is not covered :S

Thank you

Well ok pictures doesn’t seem to be uploadable today, neither in FF nor in Chrome :S

Those mean that it’s can only be loaded by using Blueprints. If you right click on the level you can set it to be always loaded or load by blueprints.

Maybe: Blueprint and volume?
