@disneyandco @LadyMichael what are your graphic settings? Mine are set to very high, and glass roofs are allowing light to pass through as expected in my game. It's possible that at a lower light setting, it might not... Also, have you checked the roof at various times of day. The interior will not be lit up the same as the outdoors even with the glass roof on; it depends upon the position of the sun outdoors as to what angle the light comes in and how strong it is, although judging by your picture, that's not the case. Let me know your settings if not on very high, and I will test it in my game.
