Toon Shading Problem.

I'm having a problem with the toon shader which when I render it, I get these weird shadows and lines in the background of my walls. Here's a picture to show what I'm talking about. :)

Here's another one, but it's on the floor.

There's a setting for toon rendering properties called "bias".

 

If it is too low it can cause that faceting appearance. High setting create very uniform lines. Low settings cause the line to vary with the severity of the surface curve it is perpendicular to. ( my observation, not a technical explanation)

 

Remember that toon rendering can be affected by either toon materials or general render settings
