Did you try the Editor Utility Widget type BP? I might be that. If it is, I don’t think it’s for runtime…
Hello, Today I discovered that there is a documentation on Level Creation nodes.
These nodes would be a big help for me with my project, creating Streaming levels in real-time would be great, or even those other nodes would help but I cannot use them anywhere, no matter what kind of blueprint I am using it will not show them. Does anyone know why or are they already deleted from the Engine, if so why there is this documentation about them?
Nevermind, got in touch with one developer, I didnt notice that there is a Editor Utility blueprint that you need to create to use this. My Bad 
Yeah, friend of mine told me about it. Didnt know there is that type of Blueprint.
