Hello,

 

a directional light is shining through terrain from below. How can I disable this?

 

Thank you

Sorry, to clarify, I am rotating the directional light.

Well it's working as intended. Since triangles are one-sided there's nothing below the terrain to block light. I'm guessing this is to make a day/night cycle, in which case the best thing to do is gradually dim the light as it approaches the horizon.
