I'm using eevee and trying to re-create Schwartz Primitive Topology found here Link but using Blender 3.1, however it's not working, any ideas why? My node setup is below.

Working Node setup: iimg1

My setup which isn't working: img2

Attached file below:

  • $\begingroup$ Probably could be faster to solve it with your blend ... If you can share. $\endgroup$

Apply scale (Ctrl+A → Scale)
