Hey there, I have a question… I just added a yet very simple Day/Night cycle to my scene. I’m doing this by simply rotating the directional light 360° around the scene and modifing its color. But as soon as the light comes from below the ground (terrain) i’m getting a light artifact. The demo cube suddenly is partially lit (see attached video from second 5 to 15)
Has anyone a suggestion how I can fix it? My terrain casts double sided shadows and I already tried with a huge quad pane. Nothing fixed it so far. Please help.
Thanks!
Have you tried reducing the light intensity (to 0) when the sun approaches the horizon to approximate sun attenuation?
yes but that doesn’t bring the desired results. When the sun goes down / rises I’d like to have the shadow casting from the terrain to the objects. If i set the intesity to 0 instantly it looks pretty weird… and this would only be a workaround … I’d be interested in a proper fix. Thanks anyway for your answer.
Any more suggestions? I also played around with the quality settings, but this doesn’t seem to be a quality issue
