Note. Unity 5 introduced the Standard Shader which replaces these shadersA program that runs on the GPU. More info See in Glossary.
Reflective shaders will allow you to use a CubemapA collection of six square textures that can represent the reflections in an environment or the skybox drawn behind your geometry. The six squares form the faces of an imaginary cube that surrounds an object; each face represents the view along the directions of the world axes (up, down, left, right, forward and back). More info See in Glossary which will be reflected on your meshThe main graphics primitive of Unity. Meshes make up a large part of your 3D worlds. Unity supports triangulated or Quadrangulated polygon meshes. Nurbs, Nurms, Subdiv surfaces must be converted to polygons. More info See in Glossary. You can also define areas of more or less reflectivity on your object through the alpha channel of the Base texture. High reflectivity is a great effect for glosses, oils, chrome, etc. Low reflectivity can add effect for metals, liquid surfaces, or video monitors.
One Base texture with alpha channel for defining reflective areas
One Reflection Cubemap for Reflection Map
One Normal mapA type of Bump Map texture that allows you to add surface detail such as bumps, grooves, and scratches to a model which catch the light as if they are represented by real geometry. See in Glossary, no alpha channel required
