Unity 2018 Shaders and Effects Cookbook - Third Edition

Getting ready

In order to get this recipe started, we need to gather a few resources together. So, let's perform the following tasks:

1. Create a new scene and fill it with a simple sphere object and single directional light.
2. Create a new shader (OptimizedShader01) and material (OptimizedShader01Mat) and assign the shader to the material.
3. We then need to assign the material we just created to our sphere object in our new scene:

4. Finally, modify the shader so that it uses a diffuse texture and normal map and includes your own custom Lighting function.

Properties {  _MainTex ("Base (RGB)", 2D) = "white" {} _NormalMap ("Normal Map", 2D) = "bump" ...
