Lighting issues when switching from Deferred to Forward

Hi all,

This is my first time using Forward rendering in UE4 and I was wondering if this is supposed to happen when switching from Deffered to Forward.

The sample scene is from a package I bought in the store but the change in lighting when I do the switch is really huge and I’m not sure if this is because I screwed up with global settings or if this is normal when doing the change and is part of the switch to re-lit everything.

Btw both are using dynamic lights at this stage.

Thanks in advance for any input and help.

Likely exposure is the issue, turn it up in your PPV
