Note. Unity 5 introduced the Standard ShaderA built-in shader for rendering real-world objects such as stone, wood, glass, plastic and metal. Supports a wide range of shader types and combinations. More info See in Glossary which replaces these shadersA small script that contains the mathematical calculations and algorithms for calculating the Color of each pixel rendered, based on the lighting input and the Material configuration. More info See in Glossary.
These shaders are the basic shaders in Unity. They are not specialized in any way and should be suitable for most opaque objects. They are not suitable if you want your object to be transparent, emitting light etc.
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. More info See in Glossary
