When ever I open TheIsland in the viewpoint the spawn volumes and ocean appear but no physical objects like “The Island” itself. Here is a picture to better understand my situation. When I hit the play button everything loads correctly but when in the editor I get the same as the image below.
In the level window, double click the levels below “persistant level” that will load each individual level, making it to where you only have to load the ones you need to.
Thanks! That is a really neat feature.
