Unite 2015 Shaders Tutorials no longer compile

Unity Engine
1

I finally decided to get into shaders today, and I started watching some tutorials on YouTube. The one I am having problems with is one taken from the Official Unity Channel, this one specifically:

The code is the exact same from the video, character by character, and the error is the following:

Shader error in '.ShaderTalk/Complete/Diffuse': invalid vs_2_0 output semantic 'NORMAL' at line 27 (on d3d9)

Compiling Vertex program
Platform defines: UNITY_ENABLE_REFLECTION_BUFFERS UNITY_PBS_USE_BRDF1 UNITY_SPECCUBE_BOX_PROJECTION UNITY_SPECCUBE_BLENDING

I also downloaded the Git source, but the error persist. Is there any possible explanation for that? The shader is the following:

Shader ".ShaderTalk/Complete/Diffuse" {
Properties
{
   _MainTex ("Main Texture", 2D) = "white" {}
   _Color ("Main Color", Color) = (1,1,1,1)
}

SubShader
{
   Pass
   { 
     Tags { "LightMode" = "ForwardBase" }
     CGPROGRAM
       #pragma vertex vert
       #pragma fragment frag

       #include "UnityCG.cginc"

       struct appdata {
         float4 vertex : POSITION;
         float3 normal : NORMAL;
         float2 texcoord : TEXCOORD0;
       };

       struct v2f {
         float4 pos : SV_POSITION;
         float3 normal : NORMAL;
         float2 texcoord : TEXCOORD0;
       };

       float4 _LightColor0;

       float4 _Color;
       sampler2D _MainTex;
       float4 _MainTex_ST;
      
       v2f vert (appdata IN)
       {
         v2f OUT;
         OUT.pos = mul(UNITY_MATRIX_MVP, IN.vertex);
         OUT.normal = mul(float4(IN.normal, 0.0), _Object2World).xyz;
         OUT.texcoord = TRANSFORM_TEX(IN.texcoord, _MainTex);
         return OUT;
       }
      
       float4 frag (v2f IN) : COLOR
       {
         float4 texColor = tex2D(_MainTex, IN.texcoord);

         float3 normalDirection = normalize(IN.normal);
       float3 lightDirection = normalize(_WorldSpaceLightPos0.xyz);
       float3 diffuse = _LightColor0.rgb * _Color.rgb * max(0.0, dot(normalDirection, lightDirection));

         return float4(diffuse,1) * texColor;
       }
     ENDCG
   }
}

}

My bad, I pasted the wrong error .-. First post updated, it does complain about declaring the normals in the v2f struct…

in the v2f struct, change NORMAL to TEXCOORD1

Well, I actually solved the problem by updating Unity, but that was a problem too :stuck_out_tongue: thank you!
