Digital-Tutors - Introduction to Scripting Shaders in Unity

We will start out by discussing the fundamentals of shaders where we'll learn about what a shader is, what shader languages are available in Unity and how to properly structure a shader. Once that is out of the way, we'll jump into creating a very simple shader to reinforce the foundation lesson. Then we'll start to add more and more functionality to our shader like how to add textures through properties. Then we'll learn about lighting models by modifying our shader to accept a specular map. We'll even add control to the inspector to adjust the overall glossiness of the shader. Finally, we'll finish off the training by adding emissive and alpha maps to our shaders.
