    Hi everybody,

    I’m asking for your help today because I have a problem with my game about rendering the terrain at night.
    I tried several manipulations by adjusting the lighting settings or turning off the shadows but I couldn’t fix the problem. It seems to me that the problem comes either from the management of light or from the shadows, since I do not have the problem when it is day. But no idea how to solve this problem... :(


    Here is the night rendering, you can see lines and rounded shapes on the ground.


    By day, I don’t have that problem.



    Here are my configurations, I generated the light well. Maybe I have a problem in my settings? The game having a day/night cycle I can not really build the light, I am forced to use a light in realtime...
    I only have one directional light.

    Thank you so much in advance for your help! :)

    Hey! If you have a very low intensity directional light, you might run into issues with cluster precision. I would suggest increasing your directional light intensity, and then using post processing to tone the image down. You could have an outdoors volume with a fixed exposure, and indoor volume(s) with a different exposure value.

    Also, have you tried precomputing using higher quality Lightmap Parameters preset? It is currently set to Default-Medium.

    As a last resort you could try clearing the GI Cache in the Preferences window.
