Checkerboard offset

Hello
I’m trying to create a sort of “wavy line” effect like here
https://pin.it/6ckBlA7

I have something that works not too bad in the file below, but the issue I’m having is that when I try to “thicken” the black lines, so they are wider than the wide lines, my strategy is not working.  I’m basically creating a second instance of a checkerboard and using blending modes to get the lines to “widen”, but it is creating some strange artefacts on render (Screenshot below).

What is the right method to do this?

Hi Alex,

Thanks for the file, thanks as well for using DropBox.

The problem with those lines will always be (!) that they are nearly “tangential” in certain areas. The more parallel they are to the surface, the more invisible the lines will be. Anyway, Use a Gradient and tile it. (…TXop_01.c4d)

The better way is perhaps to use the Noise and feed this into the UV information, so the object that has the information stays flat. Which requires the Node Editor (…NEop_01.c4d)

Click on the Material, open the node Editor. You will see the Gradient and the Noise on the left. UV Transform.2 tiles the gradient. UV Transform.1 uses the Noise to Distort the UV.
You had set the Levels to other values than 0-100, so the noise plateaus in certain areas.

All the best

P.S.: Some pointers to the Node based idea

(…TXop_11.c4d seems to be the simplest. Just set the “Cycles” in the Noise)
