I searched through the forums for how to do a setting in the night. I messed with the ambient settings, and all that did was make the tress and some models black. I tried fooling with the sky-boxes and that didn’t work. I have removed any and all lighting in the scene. i am using the island demo with this.
A few things to try…
Night time sky box
Night water
Toned down lights
Change the light color to a blue tint
Desaturate colours slightly too - night vision is much more sensitive to brightness than colour.
