Procedural Workflow: 

Making a rock with Petrify involves adding a stack of modifiers to a simple base mesh.  Once the stack is built, endless variations of that 'style' of rock can be created just by randomizing the Seed parameters.

Modular Design: 

The modifiers are modular, meaning that each does its own thing to the rock and should produce different results when combined with different modifiers or when stacked in a different order.

Rock Presets:

I have included a dozen rock presets, which are basically preset modifier stacks.  These can be used as an asset, or as a starting point to customize into your own rock, or simply as an example to learn from.

Material Variety:

Petrify comes with 6 preset materials that all provide an impressive amount of variety in the look of the materials that you can achieve with them.  

Custom Materials: 

While preset materials are great, I'm sure many of you will want to make your own, so I also included a bunch of shader nodes to assist with that.  As well as a tutorial material with notes and examples that you can experiment with to learn.

Textures: 

Petrify comes with a whole library of texture patterns to use in shaders or for displacement, there are 6 texture patterns each with 8 variations and multiple types for a total of 100+ seamless 16bit textures. (mostly 1024x1024)

Sculpting Brushes: 

Procedural rocks are great in many ways, but sometimes you need that extra level of detail and Sculpting is still the best way to achieve that.  With that in mind, I made a bunch of the heightmap textures that come with Petrify into brushes that you can sculpt with.

More Info: 

Thanks for taking a look!  I hope Petrify can turn some things into stone for you.

The Petrify library contains; 15 modifiers, 6 highly customizable preset materials, 6 utility shader nodes, 7 texture set shader nodes, 12 preset rocks, and 4 types of textured brushes for sculpting.
