Rock Generator 2

Rock Generator 2 - Houdini 16 to Houdini 19.5

(1)

Please see https://techie.se for the latest version.

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.
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.

Version 5 - Jan. 30, 2023

Updated the description.
Version 4 - Sept. 7, 2017
- Improved the way linear and random UV seams are generated.
- Changed the asset prices.
Version 3 - Sept. 3, 2017
- Added "Apply Sequentially" under "Geometry Displacement 1" > "Displacement Noises". When enabled, displacement is applied once per noise. The average point normal/curvature/normal difference is re-calculated for each noise. When disabled, all noises are added together and applied as a single displacement.
- Updated the documentation.
Version 2 - Aug. 16, 2017
- Added "Enable Displacement" (matRockEnableDisplacementParm), "Enable Bump" (matRockEnableBumpParm), "Bump Amount" (matRockBumpAmountParm), "Bump Noise" and removed "Displacement Mode" (matRockDisplacementModeParm) under "Material" > "Displacement". This allows both displacement and bump to be applied at the same time.
- Replaced the internal material node "Classic Shader Core" with "Principled Shader Core". This was done to improve the look of bump displacement.
- Renamed "Specular Intensity" (matRockSpecIntParm) to "Reflectivity" (matRockReflectivityParm) under "Material" > "Procedural Material".
- Renamed "Specular Roughness" (matRockSpecRoughnessParm) to "Roughness" (matRockRoughnessParm).
- Renamed "Affect Specular Intensity" and to "Affect Reflectivity".
- Renamed "Specular Intensity Mode" (matRockBrightnessSpecIntModeParm) to "Reflectivity Mode" (matRockBrightnessReflectivityModeParm).
- Renamed matRockBrightnessSpecIntAmountParm to matRockBrightnessReflectivityAmountParm.
- Renamed "Specular Intensity" (matBakeSpecularIntensityParm) to "Reflectivity" (matBakeReflectivityParm) under "Material" > "Baking" > "Image Planes".
- Added "Bump" (matBakeBumpParm) under "Material" > "Baking" > "Image Planes".
- Fixed an issue when enabling both material displacement and "Cusp Normals On Cracks" at the same time. It's now only possible to have "Cusp Normals On Cracks" enabled when material displacement is disabled.
- Updated the documentation.
