Unity 2018 Shaders and Effects Cookbook

How to do it...

As mentioned previously, there are a few aspects that we need to take care of while using a Transparent Shader:

1. Remove the _Glossiness and _Metallic variables from the Properties and SubShader sections of the code as they aren't needed for this example.
2. In the SubShader{} section of the shader, modify the Tags section to the following so that we can signal that the shader is transparent:

Tags 
{ 
  "Queue" = "Transparent" 
  "IgnoreProjector" = "True" 
  "RenderType" = "Transparent" 
} 

Tags are used by the SubShader to know how and when items should be rendered. Similar to the dictionary type, tags are key-value pairs where the left-hand side is the tag name and the right-hand side is the value you wish for it to be set to.
