Here's my issue. I'm trying to recreate something like this - lowpoly but flat, toon shaded objects -
What I've done is downloaded a generic toon shader, tweaked it and applied to a smooth shaded low poly object -
And you'll see around the edges, I have black lines due to the normals. I've applied Weighted Normals and it helped, and turned off ambient occlusion, but we still have this.
Here is the node graph from the toon shader:
How can I eliminate this darkness?
