Add ambient light at nighttime #1379
Comments
Completely agree with Janine. A nighttime ambient mode would be incredibly useful. Since for usability in unreal in a real-time setting we've had to either turn off the day cycle (which is a very useful feature) or be left with not being able to access the dark side of the earth. |
+1 for this. I encountered this problem when creating scenes from C++ code (performance tests). For locations very far from me (like Japan), the scene started out as completely black. I changed the time zone to fix it. Although looking back, I probably should have just set the time, and ideally the time zone would get set automatically based on where I am. Regardless, having some ambient lighting in this case would have been less disorienting. Also, not sure if the SkyLight would help us here, but here's a related issue, |
I completely agree, The pitch-black night-side rendering causes a lot of unnecessary concern. Some basic ambient lighting, even if not strictly physically accurate, would be a huge win. A built-in option with adjustable brightness would be the ideal solution in my opinion. |
Add a second directional light to represent the moon, or in our case it could just be generic light from above
This is the result from my very quick test Disclaimer that this was a 5 minute test and is no way meant to represent a physically based accurate setup. Better configurations may be found in threads such as this one. |
I think so! We have an issue for it:
Nice! |
On our community forum, many users have been confused by the pitch black screen when they view locations on the other side of the world. They interpret this as data being missing or things not rendering, when in reality this is due to the time zone settings on

.Additionally, some users have wanted night time views, but
CesiumSunSky
doesn't offer good nighttime visualization out-of-the-box. There's at least an old thread with some workarounds / material changes that can be used for better visualization (thanks @argallegos! 😄): https://community.cesium.com/t/easiest-way-to-make-a-night-time-scene/17582/.But it would be nice if there was just some ambient lighting during the night, so people could at least see a silhouette or dimly lit part of their scene. This could be an adjustable setting that scales how bright the ambient light is. It's doesn't adhere to the realistic sun model, but judging from a good number of forum posts, this would improve usability and reduce user confusion.
