Hey!
No worries, this is usually a load order bug. Just find the "VAMOverlayer" plugin on the "00_0LogicBrick" atom and manually click the "Test Fade In" button—that should fix it
I’ll remove this unstable part in the next update.
Basically, VAMOverlayer keeps the scene faded out when it loads, and the fade-in trigger is set to fire after the snapshotUI plugin finishes loading. If snapshotUI is loading for the first time, or something else gets flaky, that trigger might not fire, which leaves you with a black screen.=
Hope that helps!
