Hello,We have been having a graphical bug occur for a while now but it's
been very difficult to consistently replicate it in order to track down
what's happening. We are using Oculus's branch of the UE 4.20.3 engine.
When the bug happens the visuals ...
It has also happened when we have been testing on Rift on PC, and if it
happens in the Editor we can switch into Unlit mode with F2 and we no
longer have a black screen. If we switch back into Lit mode with F3 the
black screen returns.
