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 vertex and fragment shader with different color values for each instance. Unlike the surface shader, when you create the vertex and fragment shader you must use UNITY_SETUP_INSTANCE_ID to manually set up an instance ID.
Shader "Custom/SimplestInstancedShader"{ Properties { _Color ("Color", Color) = (1, 1, 1, 1) } SubShader { Tags { "RenderType"="Opaque" } LOD 100 Pass { HLSLPROGRAM #pragma vertex vert #pragma fragment frag #pragma multi_compile_instancing #include "UnityCG.cginc" struct appdata { float4 vertex : POSITION; UNITY_VERTEX_INPUT_INSTANCE_ID }; struct v2f { float4 vertex : SV_POSITION; UNITY_VERTEX_INPUT_INSTANCE_ID // use this to access instanced properties in the fragment shader. }; UNITY_INSTANCING_BUFFER_START(Props) UNITY_DEFINE_INSTANCED_PROP(float4, _Color) UNITY_INSTANCING_BUFFER_END(Props) v2f vert(appdata v) { v2f o; UNITY_SETUP_INSTANCE_ID(v); UNITY_TRANSFER_INSTANCE_ID(v, o); o.vertex = UnityObjectToClipPos(v.vertex); return o; } half4 frag(v2f i) : SV_Target { UNITY_SETUP_INSTANCE_ID(i); return UNITY_ACCESS_INSTANCED_PROP(Props, _Color); } ENDHLSL } }}
