Toon Shade - edge opacity issue

[CiroCardoso3v]

Playing with toon shader but I noticed that there is a issue with the edge opacity. I am using the checkered node to create a dash line, but the dash isn't clean in some areas. I have no idea why this is happening.

1. Does it happen with other maps?
2. What happens when you change the size/orientation of the checker?
3. Have you tried the checkerboard map instead?
4. How many camera (AA) samples are you using?
5. If that doesn't work, can you upload the shader somewhere?

1 - It does. I created a checkerboard map in photoshop and tiled, when I start to increase the tile number that artifact appears. I also create a gradient ramp and the same issue happens.

2 - The issue start when I start to increase the tiling, like the example here

3 - I tried the 3 options available in 3ds Max, plus a map i created.

4 - I tried with 3 up to 8 up to 16.

5 - Here you have. Forgot to mention that I am using transmission, as I need to see what is behind these objects. ToonShader.zip

Another thing. I am using transmission that I can see the box behind. Works fine when you have 1 box, but as soon you have 2 in front of it I stop seeing it. The transmission Ray depth is at 10 and I still don't see it.

Solved this one with the Arnold modifier.

I managed to get the effect I wanted. Used a Gradient Ramp with an angle and it works fine. Still would be good to understand why we are getting that weird dash line.
