I built this procedural rock system in Houdini because hand-sculpting hero rocks is fine for a handful, but when a project needs dozens of unique formations that still feel geologically plausible, you want a generator. The system creates varied rock shapes with automatic texture and detail placement. Tweak a few parameters and you get something new without starting from scratch.

It’s fully procedural, driven by Houdini and VEX. For modular asset placement along splines, see my Modular Procedural Pipes tool.
