Example Shader

Here's a simple example of a shader written in HLSL:

Shader "Custom/ExampleShader"
{
    Properties
    {
        _MainTex ("Texture", 2D) = "white" {}
    }
    SubShader
    {
        Tags { "RenderType"="Opaque" }
        LOD 100

        Pass
        {
            CGPROGRAM
            #pragma vertex vert
            #pragma fragment frag

            #include "ShaderCore.h"

            struct Input
            {
                float2 UV;
            };

            struct Output
            {
                float4 Color : SV_Target;
            };

            sampler2D _MainTex;
            float4 _MainTex_ST;

            void vert (in Input IN, out Output OUT)
            {
                OUT.UV = IN.UV;
                OUT.Color = float4(1, 1, 1, 1);
            }

            void frag (in Output IN, out float4 OUT)
            {
                OUT = tex2D(_MainTex, IN.UV);
            }
            ENDCG
        }
    }
}
