Streaming levels wont unload

**Problem solved.

The issue was the Director Fadeout track i used in let’s say Level1. When loading & unloading into Level2 the black screen of the fadeout stays! It does not reset. So keep this in mind, i was stuck a whole day at this. I finally asked myself hey, mayby it is the fadetrack? And yes it was…

My streaming levels stay loaded whatever i try

My setup:

In BP of a specific level> create *LoadStreamLevel *(name of new level to load) > create trail out of the LoadLevelStream and create UnloadStreamLevel and name it. This works in my other projects in combination with a triggerbox, and should work with a delay connected to EventBeginPlay, or after ending a Matinee it should respond to Unload & Load?

On my recent project Unloading levels dos not work, not on EndEventPlay, not using a Triggerbox with Overlapping by Actorcamera or FirstPersoncharactercamera. The Streaming levels are also not unloading when using a delay between unloading or loading the streaming level. Or by just asking to unload in BP after some specific event like a Matinee, nothing works. The levels stay loaded! Why are the streaming Levels loaded when asked for them, but when i ask to unload it does not work! Do i miss something essential here? I added some levels i already build to my persistent level and am thinking of making one huge plane full of levels where i unload and load inbetween the scenes i need.

Idea is having the whole project build as one huge connected streaminglevels farm, and one empty persistent level as root for the music data.

I have seen that Levelstreaming has changed since 2014. But after using the new Streaming level volume options menu i get a black screen when using the proper setup, not one streaming option works so far. Not with volume streaming as for unloading in BP. Only loading levels works, and this seems because they are already loaded on the beginning, even if they are switched to follow BP.
