Thanks for this. I also ran into this issue with distanceFieldAO in 4.11.1, and this thread saved me some looking around.
I can’t used DistanceFieldAO as it isn’t working yet with VR and instanced stereo rendering so i was trying to disable it.
For now, I’ve re-enabled DistanceFieldAO with “r.DistanceFieldAO 1” and “showFlag.DistanceFieldAO 1”
in my game instance, and that seems to work with setting the DistanceField AO settings at 0 in the skylight as a
temporary workaround. Will be looking forward to the fix.
