Iray SS Night Color?

Could someone explain what the SS Night Color is for? I can't get it to have any effect on a scene. Thanks in advance.

    As far as I know it should set the colour of the sky in the Iray Dome when the time is set for darkness in the time zone set under Environment. I have mine set for a deep/nearly black blue.

    That's what I thought, but I get a pitch black screen no matter what color I set that to when I set the time to night.

    You have to then set the Tone Mapping high to get the colour, you wont get light though as there wont be enough coming from the dome. I had to set F/stop to 2, Shutter Speed to 1 and ISO to 800 and all I got was a weak blue glow on the horizon :) That was for the Northern Hemisphere, 21st December and half past Midnight.

    Thanks, that did make...the dome and floor very slightly visible. Pretty useless feature if you still have to simulate a night scene with spotlights and other 'fake' methods though. Anyway, thanks for the information.

    well it isn't fake when you think of the logic that Iray is Photoreal, best to use 3DL. ;)

    Well *technically* it's not fake, but since it doesn't allow moonlight (as far as I know), it's not entirely real (and still quite useless).   ;)

    LOL This is true it would make the moon a bright spot given how much light a real camera needs. This is why 3DL was best at doing that yype of image

    I use a distant light to simulate moonlight. You wont get light from the sky unless you add some, as in real life. I have walked at night with deep cloud cover and no light and couldn't see my hand in front of my face :)

    A quick render where I changed the time to midnight, used a distant light at Temperature 10000K, Lumen of 5.00, Tone Mapping at Speed 1second, F/Stop 2.8, ISO 800, Saturation 0.5 and white balance towards the red. I changed the sky colour to a lighter blue to make it more visible. It could do with more work to make it better though :)
