Question by somejonus · Nov 28, 2016 at 11:58 AM · shaderiosshadowsshaderlab

CG >shadow catcher< shader not showing in iOS

I have this shader on two planes. It makes them transparent and only shows the shadow they receive. However, compiling and running it on iOS makes the shadows go away and I cant figure out why. Any ideas?

 Shader "FX/Matte Shadow" {
  
 Properties {
  
     _Color ("Main Color", Color) = (1,1,1,1)
  
     _MainTex ("Base (RGB) Trans (A)", 2D) = "white" {}
  
     _Cutoff ("Alpha cutoff", Range(0,1)) = 0.5
  
 }
  
 
 SubShader {
  
     Tags {"Queue"="AlphaTest" "IgnoreProjector"="True" "RenderType"="TransparentCutout"}
  
     LOD 200
  
     Blend Zero SrcColor
  
    
 CGPROGRAM
  
     #pragma surface surf ShadowOnly alphatest:_Cutoff
 
 
 fixed4 _Color;
  
 struct Input {
  
     float2 uv_MainTex;
  
 };
  
  
 inline fixed4 LightingShadowOnly (SurfaceOutput s, fixed3 lightDir, fixed atten)
  
 {
 
     fixed4 c;
  
  
     c.rgb = s.Albedo*atten;
  
     c.a = s.Alpha;
  
     return c;
  
 }
  
 
 void surf (Input IN, inout SurfaceOutput o) {
  
     fixed4 c = _Color;
  
     o.Albedo = c.rgb;
  
     o.Alpha = 1;
  
 }
  
 ENDCG
  
 }
  
 Fallback "Transparent/Cutout/VertexLit"
  
 }
