At daylight setting for environment, everything goes well. But when I try to create a night environment. I realized problem of material render without light
I turn off Sun and Ambient in Environment setting. Expect getting a pit black map because there is no light at all, but look at all material, they are shining
It is worse if material has high Smoothness and Refectivity value. setting both of them to 0 does not help. Reducing Normal value can make material look much "dark" but it affects material quality on "day light".
After reduce all above 3 values to 0, the ground material still look shiny at far range.
Anyway, I cant reduce every material because it make my game's material broken
How can I create a real night ? how to solve the shiny material problem
btw, why does the cloud look so ugly, and many partical effect is broken at night time
