How do you use StreamingPauseRendering

I have been looking through the code to see how I can implement/use StreamingPauseRendering which was added in 4.2.

If I am not mistaken this should hopefully show a throbber slate UI widged (animated) while the level is being loaded using OpenLevel. That would be exactly what I am looking for.

However I am absolutely clueless as to how to actually enable this state in C++ and/or Blueprint.

There does not seem to be any information regarding this piece of code to be found online so I am helpful for any advice.

Thanks.

Same here!

Out of curiosity. Why some questions like this are completely ignored by the Staff?
