Question Shader error in 'SG/SG Reflect': Duplicated input semantics can't change type, size, or layout ('TEX

do you know what that means and how to fix it?

Code (CSharp):

1. Shader error in 'SG/SG Reflect': Duplicated input semantics can't change type, size, or layout ('TEXCOORD0').
2.  
3. Compiling Fragment program with FOG_EXP2
4. Platform defines: UNITY_ENABLE_REFLECTION_BUFFERS UNITY_USE_DITHER_MASK_FOR_ALPHABLENDED_SHADOWS UNITY_PBS_USE_BRDF1 UNITY_SPECCUBE_BOX_PROJECTION UNITY_SPECCUBE_BLENDING UNITY_ENABLE_DETAIL_NORMALMAP SHADER_API_DESKTOP UNITY_COLORSPACE_GAMMA UNITY_LIGHT_PROBE_PROXY_VOLUME UNITY_LIGHTMAP_RGBM_ENCODING
5.  

the shader is this

Code (CSharp):

1.   Shader "SG/SG Reflect" {
2.     Properties {
3.     [HDR]        _Color ("Color",Color) = (1,1,1,1)
4.       _MainTex ("Texture", 2D) = "white" {}
5.       //_Cube ("Cubemap", CUBE) = "" {}
6.         _Metallic ("Metallic", RANGE(0,1)) = 0.5
7.         _Smoothness ("Smoothness", RANGE(0,1)) = 1
8.       _HealColor ("Heal Color", Color) = (0,1,0,1)
9.       _HealPulseVal ("Heal Pulse", RANGE(0,1)) = 0
10.       _DamageColor ("Damage Color", Color) = (1,0,0,1)
11.       _DamagePulseVal ("Damage Pulse", RANGE(0,1)) = 0
12.      _OutlineColor ("Outline Color", Color) = (0,0,0,1)
13.     _Outline ("Outline width", float) = .005
14.         }
15.    
16.     SubShader {
17.       Tags { "RenderType" = "Opaque" }

35.           float3 vertexColor;
36.           float3 viewDir;
37.       };
38.          
39.       void vert (inout appdata_full v, out Input o)
40.       {
41.           UNITY_INITIALIZE_OUTPUT(Input,o);
42.           o.vertexColor = v.color.rgb;
43.       }
44.

46.       samplerCUBE _Cube;
47.      
48.       void surf (Input IN, inout SurfaceOutputStandard o)
49.       {
50.              half3 c = tex2D (_MainTex, IN.uv_MainTex).rgb * IN.vertexColor *2* _Color;        
51.              c = c*(1-_DamagePulseVal) + _DamagePulseVal*_DamageColor.rgb;      
52.             c = c*(1-_HealPulseVal) + _HealPulseVal*_HealColor.rgb;
53.           c *= IN.vertexColor;
54.             o.Albedo = c;
55.           o.Smoothness = _Smoothness;
56.           o.Metallic = _Metallic;
57.       }
58.       ENDCG
59.      UsePass "Toon/Basic Outline/OUTLINE"
60.     }
61.    
62.     Fallback "Diffuse"
63.   }

 

Did you figure it out? i have the same problem!

 

Just a wild guess, but maybe check if you are using the same semantic twice. For example SV_Position and POSITION could be the same as well as TEXCOORD_0 and UNITY_FOG_COORDS(0).

 

I fixed it but that was so long ago I don't remember.
Lemme exhume that old project.
Oh I switched to URP and rewrote the shader in SG.
Sorry can't help on this one.
