Skylight Reflections Problem

I’m having an issue with Skylight and Reflection Captures in which they capture the environment pitch black, only lit up by the fog.
Really don’t know how to explain it any better.

It happened after updating to UE 4.9 as far as I remember.

Any ideas why this is happening?
