Question by honeywaffles · Nov 23, 2014 at 02:19 PM · shaderterraingrasscustom-shader

Shader LOD wont work on custom grass shader

I have edited the grass shader that comes with unity, and tried to implement LOD, but failed.

 Shader "Hidden/TerrainEngine/Details/WavingDoublePass" {
     Properties {
         _MainTex ("Base (RGB) Transparency (A)", 2D) = "" {}
         _Cutoff ("Alpha cutoff", Range (0,1)) = 0.5
     }
 
 SubShader {
     Tags {
         "Queue" = "Geometry+200"
         "IgnoreProjector"="True"
         "RenderType"="Grass"
     }
     LOD 700
     Cull Off
     ColorMask RGB
         
     CGPROGRAM
     #pragma surface surf Lambert vertex:WavingGrassVert noforwardadd
     #pragma exclude_renderers flash
     #include "TerrainEngine.cginc"
 
     sampler2D _MainTex;
     fixed _Cutoff;
 
     struct Input {
         fixed2 uv_MainTex;
         fixed4 color : COLOR;
     };
 
     void surf (Input IN, inout SurfaceOutput o) {
         fixed4 c = tex2D(_MainTex, IN.uv_MainTex) * IN.color;
         o.Albedo = c.rgb;
         o.Alpha = c.a;
         clip (o.Alpha - _Cutoff);
         o.Alpha *= IN.color.a;
     }
     ENDCG
 }
 
 SubShader {
     Tags {
         "Queue" = "Geometry+200"
         "IgnoreProjector"="True"
         "RenderType"="Grass"
     }
     LOD 1000
     Cull Off
     ColorMask RGB
         
     CGPROGRAM
     #pragma surface surf Lambert vertex:WavingGrassVert noforwardadd addshadow
     #pragma exclude_renderers flash
     #include "TerrainEngine.cginc"
 
     sampler2D _MainTex;
     fixed _Cutoff;
 
     struct Input {
         fixed2 uv_MainTex;
         fixed4 color : COLOR;
     };
 
     void surf (Input IN, inout SurfaceOutput o) {
         fixed4 c = tex2D(_MainTex, IN.uv_MainTex) * IN.color;
         o.Albedo = c.rgb;
         o.Alpha = c.a;
         clip (o.Alpha - _Cutoff);
         o.Alpha *= IN.color.a;
     }
     ENDCG
 }
 
 SubShader {
     Pass {
         Material {
             Diffuse [_Color]
         }
         Lighting Off
         }
     }
 }

If I change the LOD to 700, the grass keeps having shadows, if I turn it even a unit lower, the grass becomes black. I cant figure out why it does this? Can anyone help me?
