Is there a projection for this kind of effect? [SOLVED]

#1

I was watching a tutorial in World Machine and my eye caught this

Is there a way to make a gradient follow the geometry expanding and contracting like in that screenshot ?
(I mean if I had to make a biorama like that, cause if it’s a spline made ribbon then it’s easy cause the UVs are there, but to make the above I’d have to use a boole)

I think this “strata” effect is simply a side product of a distorted mesh on a straight UV gradient.

Take a UV mapped cube and add a gradient to its side, then subdivide and sculpt to top part, and you’ll see the valleys squash the side gradient, while the peaks will stretch it.

I was looking for a parametric solution.
I’ve managed to make it posible.
