Stone materials for Cycles

2015-03-21 19:56 (source code)

This is a collection of rock materials for the Cycles engine in Blender. I have tried to reproduce the look of a variety of real rock types. They are quite detailed and are best used at close-up range.

Since one type of geologic rock can look quite differently depending on its detailed composition, and its impurities, I have included multiple variations for many rock types. The materials are free to use and modify, and you can see how they are done in the node editor.

Igneous rocks

Gray granite rock surface — Gray granite. The black spots may look strange at first, but real granite has them.

Brown granite rock surface — Brown granite.

Red granite rock surface — Red granite. In this one the black and reddish spots occur in clusters. This is accomplished by modulating those colors with both a small scale noise node (creating the individual spots) and a large scale one (creating the clusters).

White granite rock surface — White granite.

Diabase rock surface — Diabase.

Gabbro rock surface — Gabbro.

Bright basalt rock surface — Bright basalt. Basalt is frequently full of holes like a swiss cheese, or it can even have an interesting columnar structure. These shapes would probably have to be modeled rather than being included in the material.

Dark basalt rock surface — Dark basalt.

Pure obsidian surface — Obsidian.

Obsidian surface with brown impurities — Obsidian with brown impurities.

Sedimentary rocks

Bright sandstone rock surface — Bright sandstone.

Yellow sandstone rock surface — Yellow sandstone.

Orange sandstone rock surface — Orange sandstone.

Red sandstone rock surface — Red sandstone.

Pale limestone rock surface — Pale limestone.

Gray limestone rock surface — Gray limestone.

Brown limestone rock surface — Brown limestone.

Claystone rock surface — Claystone.

Claystone rock surface with white impurities — Claystone with white impurities.

Claystone rock surface with yellow impurities — Claystone with yellow impurities.

Pure chalk rock surface — Pure chalk.

Chalk rock surface with yellow impurities — Chalk with yellow impurities.

Chalk rock surface with yellow and gray impurities — Chalk with yellow and gray impurities.

Metamorphic rocks

Brown gneiss rock surface — Brown gneiss.

Red gneiss rock surface — Red gneiss.

White gneiss rock surface — White gneiss.

Polished black and white marble surface — Black and white marble. The marbles are rendered on a polished surface since they look more beautiful that way.

Polished blue and white marble surface — Blue and white marble.

Polished brown marble surface — Brown marble.

Polished green marble surface — Green marble.

Polished white marble surface — White marble.
