Issue with lighting and volumetric fog

Hi

My lighting and volumetric fog stopped w
This issue happens only on my computer but I am not sure how to go about solving it.

It only started happening recently and it happens with both 4.16 and 4.17.

This wasn’t always an issue.

This is how the file is supposed to look.
I tested it on other computers and it works fine.
I would greatly appreciate any help I can get.
Many thanks

Hi tried this twice, no changes

Hello, tried that, did work. Using nvidia gtx860m Atm

reinstalling ue4 helped me with a similar issue. not a proven method tho
