The Built-In Render Pipeline is deprecated and will be made obsolete in a future release.
It remains supported, including bug fixes and maintenance, through the full Unity 6.7 LTS lifecycle.
For more information on migration, refer to Migrating from the Built-In Render Pipeline to the Universal Render Pipeline and Render pipeline feature comparison.
The following example demonstrates how to create an instanced Surface Shader with different color values for each instance.
Shader "Custom/InstancedColorSurfaceShader"{ Properties { _Color ("Color", Color) = (1,1,1,1) _MainTex ("Albedo (RGB)", 2D) = "white" {} _Glossiness ("Smoothness", Range(0,1)) = 0.5 _Metallic ("Metallic", Range(0,1)) = 0.0 } SubShader { Tags { "RenderType"="Opaque" } LOD 200 CGPROGRAM // Uses the physically based standard lighting model with shadows enabled for all light types. #pragma surface surf Standard fullforwardshadows // Use Shader model 3.0 target #pragma target 3.0 sampler2D _MainTex; struct Input { float2 uv_MainTex; }; half _Glossiness; half _Metallic; UNITY_INSTANCING_BUFFER_START(Props) UNITY_DEFINE_INSTANCED_PROP(fixed4, _Color) UNITY_INSTANCING_BUFFER_END(Props) void surf (Input IN, inout SurfaceOutputStandard o) { fixed4 c = tex2D (_MainTex, IN.uv_MainTex) * UNITY_ACCESS_INSTANCED_PROP(Props, _Color); o.Albedo = c.rgb; o.Metallic = _Metallic; o.Smoothness = _Glossiness; o.Alpha = c.a; } ENDCG } FallBack "Diffuse"}
