Tutorial: Intuitive material building with the UI Material Lab - Part 3

hi, sorry I posted the wrong reference screenshot before, What I am after is a checker (2d square shapes ) noise material function to be used in UI materials and surface materials for shields,
in Fortnite Shields and maps had some kind of checker noise, and the cube scaling effect is smooth, but I can’t achieve that kind of smoothness.
the below screenshot map had transparent cubes.

I’m using a noise texture for the square scaling effect,

when using the MF_UI_RANDOM node

in the below screenshots, each square’s width and height are different, and even the grid tile position is offset a little, how to achieve this?

Another question is. how do names string for locations, are those textures arrayed inside material or UI RichText ?
