Unity 5 Toon Shader Terrain?

I’ve been trying out different toon shaders. However, I keep running into one issue. I can’t find a toon shader that will work with the terrain. I’ve read and got the code from a tutorial for custom terrain shaders. I’ve applied it, yet it does not work and keeps saving back to the default specular terrain shader?

Is there anyway to make this work, or will I have to rethink my environment?

  1. I found this tutorial to be the answer: Next-Gen Cel Shading in Unity 5
  2. I found out the normal map for my terrain texture was working when I toggled with the smoothness.
