Async level loading is not working

I am now making a level transition with async asset loading to minimize block of “Open Level”.

So, i added codes about loading assets which are included in target level from DefaultGame.ini. (StaticMeshs, particles, umap)
(AssetLoad → Done? → OpenLevel)

I succeeded assets load, but there is no change on “open level”'s delay time.

I got some time data using “UE Insight”, they(async case, just open lvl case) are all 3.0s.

There are no difference even i apply async asset load…,

Did i implement in wrong way…?

I want to know why async loading is not working in Open Level effectively.


(left one : Just calling “Open Level” / right one : Calling “Open Level” after async loading done)
