Trying to make Toon Shader Material on UE4

Yes and I’ve tried to rebuild the lighting multiple times. Using a Lightning Model rather than a World Normal seems much better since the light seems to be hitting from the right angle and cast shadows where they should be. The only thing I need to fix now is the weird artifacts in the shadows(the darker areas within the shadows).


You can see it in the shadow behind the rocks as well as the brushes. Do you know how to fix this ElliotB?
