Hi all,

I’m trying to create concentric, layered geometry—similar to the layers of an onion—with a striped structure (and potentially multiple colours later on).

In the HIP file below, I’m using a letter “F” as the base shape. The goal is to slice through the geometry using a Clip SOP, so that the cross-section cleanly reveals the internal layers, like cut-through playdough.

HIP file:

I’ve made some progress, but I’m not yet getting the result I’m after—the layers aren’t being exposed cleanly or consistently in the clipped cross-section.

I’d really appreciate any advice on the correct SOP-level approach for constructing and revealing this kind of layered geometry.

Thanks!

You might have better luck using PolyExpand2D to generate the concentric slices. You could possibly take the resulting geometry, run them through an Ends SOP to turn them into curves, then extrude those as edges and work from there to get the inner geometry you're looking for.
