Procedural Rock Generator Lite

Rock Generator Lite is a free procedural rock generation tool for Unity. It lets you create custom rock meshes, bake texture maps, generate clean prefabs, and test simple terrain scattering workflows directly inside the Unity Editor. This Lite version is intended as the entry point for the Rock Generator workflow. It is useful for testing the generator, learning the controls, and creating individual rock assets. If the workflow fits your project and you want to use it in a larger production environment, Rock Generator Pro is the recommended upgrade. Rock Generator Pro includes the Lite workflow and expands it with batch generation, a more advanced placer, local brush placement, higher texture resolutions, more generation and texturing options, runtime-oriented tools, and material/texture atlas combining. Generated Rocks Are Yours The rocks you generate with this tool are your generated output assets. You may use, modify, sell, and redistribute generated rock meshes, materials, textures, and prefabs in your own games, demos, scenes, rendered media, asset packs, or commercial projects. This permission applies to generated output assets. It does not grant permission to redistribute the Rock Generator Lite or Rock Generator Pro package, source code, editor tools, compute shaders, documentation, demo scripts, or other original package files. Generated baked rocks are saved as normal Unity assets. The output can include prefabs, meshes, materials, texture maps, LODs, and optional colliders. Baked output uses standard Unity material paths where available, including URP Lit, HDRP Lit, and the Built-in Standard shader fallback. Once generated, baked rock prefabs do not require Rock Generator Lite MonoBehaviours to function as normal environment assets. Lightweight Package, Generated Output Rock Generator Lite does not ship with pre-made rock meshes, large texture libraries, or finished rock prefab libraries. The package is small because the included rocks are generated from code-based presets and procedural settings. The package includes 35 quick-start mathematical presets. These presets are intended as starting points that can be edited, randomized, and regenerated with different seeds. Preset styles include standard environment rocks and more stylized mineral or biome examples, such as: • Alien Geode • Deep Sea Hydrothermal Vent • Geometric Bismuth Cluster • Frost-Rimed Alpine Spire • Scorched Meteorite • Banded Iron Formation • Folded Metamorphic Schist Because the generator is seed-based, each preset can produce a wide range of related variants. The goal is not to ship a fixed rock library, but to let you create the rock assets your project needs. Core Rock Generation Rock Generator Lite starts from a procedural base shape and applies configurable displacement, proportions, and noise controls. Main shape controls include: • Base Topology: Choose between Icosphere and CubeSphere base shapes. Icosphere works well for rounder boulders and organic shapes. CubeSphere is useful for blockier formations, slabs, pillars, and structural rock forms. • Size and Proportions: Control target diameter, prefab scale, fixed proportions, or seed-based randomized proportions. • Macro and Detail Noise: Shape the large silhouette separately from the smaller surface breakup. • Fractal Modes: Use Standard, Billow, Ridged, PingPong, and Swiss Erosion modes to create different displacement behavior. • Domain Warping: Add folded or flowing distortion for compressed or metamorphic-style shapes. • Voronoi: Create cellular cracks, facets, and mineral-like forms. • Terracing: Create stepped and layered shapes for sedimentary rocks, slabs, and cliffs. LOD generation is built into the prefab output. Rather than relying on a general mesh-collapse operation, the generator creates LOD meshes from different procedural resolutions. This helps keep the LODs predictable and avoids some of the UV and normal problems that can come from blind mesh reduction. Procedural Text
