Question by ToyBoya · Feb 19, 2016 at 10:33 PM · shaderterrainmaterialspotlightpoint light

Point/Spot lights only emit half of the light on my terrain

I'm designing my level on a terrain, but my point lights and spot lights only shine on half of their hemisphere. Lights work fine on a plane though.

What could it be? I've already tried:

  • Changing Pixel Light Count in Quality Settings.

  • Playing with my Terrain's material and texture

  • Changing Rendering Path to other than Forward in Player Settings

  • Playing with Environment Lighting options

I've read similar topics, but most of them had no solutions and those who had, didn't help me. I hope somebody will know the solution by now. Thanks!

Apparently it happens when I put a normal texture in terrain's texture painting. Maybe because I put a wrong texture for a normal texture, not sure. But removing a normal texture from terrain's texture painting fixed this.

I've solved this problem long time ago. The solution for me was to simply unpack normal map in Amplify Shader Editor if I remember correctly. Don't know how to do that without ASE asset

I was having this issue recently with the ceiling of my scene. Checking the "Create from Grayscale" in normal map texture settings fixed the issue.,I was having this issue recently with the ceiling of my scene. Changing the normal map to "Create from Grayscale" fixed the issue.

@Asterozoa: In my case It is NOT changing to "Normal" when I try to change the Texture Type, nor is the Fix It Now button doing anything!! When I hit "Apply" the changes revert to Default and the Message: "This Texture is not marked as a Normal" appears again!!! Please HELP!!!
