Final color modifier Surface Shader example in the Built-In Render Pipeline

It is possible to use a “final color modifier” function that will modify the final color computed by the ShaderA program that runs on the GPU. More info
See in Glossary.The Surface ShaderA streamlined way of writing shaders for the Built-in Render Pipeline. More info
See in Glossary compilation directive finalcolor:functionName is used for this, with a function that takes Input IN, SurfaceOutput o, inout fixed4 color parameters.

Here’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 LightmapsA pre-rendered texture that contains the effects of light sources on static objects in the scene. Lightmaps are overlaid on top of scene geometry to create the effect of lighting. More info
See in Glossary, Light ProbesLight probes store information about how light passes through space in your scene. A collection of light probes arranged within a given space can improve lighting on moving objects and static LOD scenery within that space. More info
See in Glossary and similar extra sources.
