For a prototype game design, our team needed an effect for revealing hidden objects in game using a special kind of light.
I built out custom blueprints for both "Revealing" and "Natural" lights
These lights would both send information to custom materials and effects I created which allows hidden objects to react to being hit by these different kinds of lights. Having the setup broken down into these modular pieces allowed design to create various puzzles easily and allowed environment artists to swap in meshes and textures as they were developed.
