Procedural rock generation with Mesh and Geometry Nodes workflows, advanced distributions, and surface scatter tools.
Part of the DRH Add-ons ecosystem - Blender tools, updates, and releases.
DRH - Rock Studio helps Blender users generate procedural rock assets as Mesh objects or Geometry Nodes setups, then arrange them using predefined 2D and 3D placement patterns.
This repository is the central public hub for support, documentation, issue tracking, compatibility feedback and future development updates while active development is on hold.
If DRH - Rock Studio helps you work faster or makes your Blender workflow more reliable, you can support ongoing DRH development on Ko-fi. Your contribution helps fund maintenance, Blender compatibility updates, documentation, testing, and the development of new production-focused tools across the DRH ecosystem. Support is completely optional, and bug reports, compatibility feedback, and workflow suggestions are always welcome.

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.
Instead of modeling every rock manually from scratch or arranging assets one by one, DRH - Rock Studio helps turn rock creation and placement into a faster, more adjustable, and repeatable workflow.

DRH - Rock Studio helps you create, configure, and arrange rock assets directly inside Blender.
It is not only a simple object preset tool. It is designed as a workflow helper for generating rock forms, choosing between Mesh or Geometry Nodes output, creating variations, and placing rock arrangements using predefined 2D and 3D layouts.
Use it to:
- Generate rock assets faster
- Create rocks as Mesh objects
- Create rocks as Geometry Nodes setups
- Build natural-looking shape variations
- Use predefined 2D placement arrangements
- Use predefined 3D placement arrangements
- Explore procedural rock forms
- Build environment props and terrain details
- Reduce repetitive manual modeling and placement work
- Create reusable rock variations for scenes
- Support asset creation for games, renders, kitbashing, or BlendKit-style workflows
- Generate procedural rocks as Mesh or Geometry Nodes assets
- Massive placement system with 2D, 3D, and on-surface scatter workflows
- Ready-made rock presets for rapid environment production
- Procedural variation controls for more natural and less repetitive sets
- Surface scatter and drop tools for faster scene dressing
- Auto Apply and manual Apply Changes workflow for heavy rebuild safety
- User preset storage on disk and inside the blend file
- LOD and preview density controls to balance speed and detail
