can not open Level Variant Manager

I also placed this on Answers Hub but it does not seem to get used much so placing it here too.

I am trying to use LevelVariantSet as to the videos posted changing wheels etc.

when I create a LevelVariantSet name it whatever I want and then double click it NOTHING happens the manager doesn’t open up, no windows open up or anything, I have tried this in 4.24 and 4.25 and it is the same on both version.

I am now stuck and not sure what to do with this and there is no information online for bug’s or error’s on this matter.

in the output window, all I get is… “LogAssetEditorSubsystem: Opening Asset editor for LevelVariantSets /Game/NewSet.NewSet” but then nothing.

Hope someone can help


you would need to enable the Variant Manager Plugin for your Project.To use the Variant Manager

Hi there, I have a similar issue. Had a working Level Variant Set and all of a sudden I can’t open it up to make changes to it. The Plugin is enabled and the game still works with what I’ve done inside the Variant Manager so far, but I can’t open and view the window. Can’t find any solutions out there.

I’ve also uninstalled and reinstalled Unreal (using version 4.25).

Any help would be greatly appreciated. Cheers.
