According to the forums the ARMA team have been tweaking interior light levels in their games
This absolutely needs to find its way into DAYZ as the interiors are very immersion breaking
In my opinion we need to be in a scenario where its is necessary to use torches and flashlights when we go deep indoors or underground.
Or DAYZ needs to develop its own automatic light blocking technology for interiors
And it must not be allowed to be turned off by the cheats.
For example PU battlegrounds seems to look pretty good in this respect.
