-I’ll try repro-ing it in a blank project, but my project is content-only and doesn’t do anything weird with level streaming, so I highly doubt it’s project specific.
-Just try to stream in a level from the level blueprint, with ShouldBlockOnLoad=true. It won’t be a blocking load.
-That’s not possible, no. I can see the level loading in around me over time, as is expected with a non-blocking load. The desired lag/hitch isn’t minimal, it doesn’t happen.
Is it possible that the reason you haven’t been able to repro is that you’re not using a big enough map? On a small map that doesn’t take much time to load, a non-blocking load is pretty much indistinguishable from a blocking one, after all.
