DRH - Rock Studio

Procedural rock generation with Mesh and Geometry Nodes workflows, advanced distributions, and surface scatter tools

---

Overview

DRH - Rock Studio is a Blender workflow utility designed to help users create procedural rock assets, choose between Mesh or Geometry Nodes output, explore shape variations, and arrange rocks using predefined 2D and 3D placement layouts.

It is intended for environment artists, asset creators, game artists, procedural artists, scene builders, and Blender users who need rock forms for natural scenes, terrains, props, kitbashing, scattering layouts, or visual development.
