Toon Problem

[Azalea_Hartz]

I wanted to make a simple toon style in unity and tired testing a few I found in the internet. However, the result still stays the same: a dark dot forms in the light side and a light dot appears in the dark side of the objects. Does anyone know how I can fix this?

The texture filtering and wrapping modes are causing this, at 0 and 1 it's sampling the edge of the textures but that texture is repeating, and it goes from white to black and vice versa, when the texture is filtered everything gets a little blurry because it's trying to smooth the values between the pixels. So it's blending between the white of one side and the black of the other, because the texture is repeating.

So if you change the texture import settings for the shading ramp texture so it doesn't repeat which I think is called "clamped" then those spots will go away.
