How can I preload a level when not using Level Streaming?

Hi Guys,

I am working on a game which uses multiple levels. When switching to the next level I want it to be preloaded while the current level is still active and playable and not covered by a loading bar widget to cover up the transition.

I know how to do this with Level Streaming but was wondering if it is even possible when not Level Streaming.
I am NOT using Level Streaming for reasons I don’t want to get into here to spare you these details.

Help much appreciated! THX!

Not possible without level streaming I’m afraid…

okay, thought so. THX for your reply!
