    Hi everyone,
    I have a project where I can change the Day/Night light by a UI Button. To do this I switch between 2 different directional light and 2 different SkyBox materials.
    Said that i don't understand why some light stop working when it becomes "night". I have a car moving on the scene and its lights work perfectly during the "Day" but not in the "Night".

    I Attached some images that show how the asphalt is rendering during the different daytime. In the "night" the light is rendering only on the LineRenderer (the asphalt white segment) but not on the real asphalt.

    Any idea on why this is happening?

    I suspect you might be running into pixel light limit. I wrote a chapter on this in the Lightmapping Troubleshooting Guide.

    That actually worked, the problem where too many lights and the "Auto" setting.
    I've changed some lights into emissive textures and now everything works properly without even flickering.
    Thank you!
