How to setup "Standard (Specular Setup)" shader for a scene

I am using this library https://www.assetstore.unity3d.com/en/#!/content/49547 from the asset store to load a obj at runtime using C#. However as per the comments given there the code only works if there is a particular Shader(Specular Setup) in the scene.

I tried to select the shader in Edit Menu > Project Settings > Graphics settings as per the attached image but no avail. Any suggestions would be appreciated.

Anybody? any ideas?
