How do I get the right Lighting/Brightness in and out of Cockpit in VR?!

[Lurker]

So just like the title says I would really like some tips for getting the brightness sorted out in VR. Im using the Rift S, and with the default gamma the brightness outside the cockpit is just too high...

 

Any tips to get good brightness/lighting settings inside the cockpit and outside as well, or is that impossible in VR currently? 

 

Also unsure of what Global Illumination does, anyone know for sure? 

 

Thanks in advance.
