It is possible to use a "final color modifier" function that will modify the final color computed by the Shader.The Surface Shader compilation directive is used for this, with a function that takes parameters.
finalcolor:functionNameInput IN, SurfaceOutput o, inout fixed4 colorHere's a simple Shader that applies tint to the final color. This is different from just applying tint to the surface Albedo color: this tint will also affect any color that comes from Lightmaps, Light Probes and similar extra sources.
Shader "Example/Tint Final Color" { Properties { _MainTex ("Texture", 2D) = "white" {} _ColorTint ("Tint", Color) = (1.0, 0.6, 0.6, 1.0) } SubShader { Tags { "RenderType" = "Opaque" } CGPROGRAM #pragma surface surf Lambert finalcolor:mycolor struct Input { float2 uv_MainTex; }; fixed4 _ColorTint; void mycolor (Input IN, SurfaceOutput o, inout fixed4 color) { color *= _ColorTint; } sampler2D _MainTex; void surf (Input IN, inout SurfaceOutput o) { o.Albedo = tex2D (_MainTex, IN.uv_MainTex).rgb; } ENDCG } Fallback "Diffuse" }
Shader example that uses the final color modifier method.
