Trying to make Toon Shader Material on UE4

Hey i really like your shader, thanks for sharing. I was trying to see if you could help me though when i try to use the new 3d widgets they come out grayed out. This is also the case with particles. I tryed to put back what the shader took out in there own blue print NO go. I also tryed to split into two objects and leaving of custom render NO Go. Any ideas would be greatly appreciated.
