Rock Generator 2.7

0 ratings

This is a Houdini SOP node asset that generates rock geometry with UV coordinates and a material.

The procedure is as follows (each step can be turned on/off):

  • Select a base shape, either a sphere, a randomly generated shape or use input geometry.
  • Transform the base shape.
  • Apply remeshing and smoothing.
  • Displace the base shape with various noises. There are five different types of displacements that can be applied and each type can use multiple types of noises.
  • Add details such as small rocks or crystals on the rock surface.
  • Apply an additional transform.
  • Apply additional remeshing and smoothing.
  • Apply polygon reduction.
  • Create UV coordinates.
  • Apply a final transform.
  • Apply a procedural material which can also be baked to a file.

The material is provided as a separate SOP node asset since it needs access to the geometry to calculate some attributes used by the material.

Version: 2.7

Date: 22 March 2020

Supported Houdini version: 16 and later

The asset is provided as either a locked/blackboxed HDA (the nodes inside cannot be viewed/edited) or unlocked (editable) HDA file and can be used in Houdini FX, Core, Indie and Apprentice. Both versions contain the same features.


  • You may use the asset for both non-commercial and commercial purposes.
  • The locked/blackboxed (non-editable) asset file is licensed for one user. The file is not locked to a specific computer and may be copied if needed.
  • The unlocked (editable) asset file may be used by multiple users at the same company, however it is appreciated if one file is purchased per user.
  • You may not make the asset file available for download elsewhere, by itself or as part of another asset or project.

Note: the video is from version 1.5 and a lot of improvements and changes have been done since then.
