Crazy test with Cycles nodes to understand procedural alpha masks

One UV unrapped object with this cycles material.
What do you think?

I’ll have more thoughts if you share what it looks like rendered

Have you checked outputs from Ramp and Invert nodes? Why 2 Transparent nodes? Also more clear would be using just a Color or Fac outputs from Checker (one node) imho.

Didn’t check outputs the way you expose. Yes, one transparent is enough, just for study the subject, cause it was dificult for me to get this result with the transparencies. Latter i’ll clean it.
Thank’s for the tip.

It doesn’t have must impact rendered. It´s more like a function.
