Example 1

Example 2

This is a SOP node 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 since it needs access to the geometry to calculate some attributes used by the material.
