Rock Shaper – Stylized Rock Editor & Mesh Generator

Rock Shaper is a Unity Editor tool for generating custom stylized rock meshes directly inside Unity.

Start from a preset or random seed, then shape the result into your own rock design using artist-friendly controls for silhouette, proportions, surface detail, cracks, fractures, and color.

The main feature is silhouette control. Instead of being locked to a fixed rock pack or a one-click random result, you can reshape the generated mesh directly in the Scene View using cage handles. Stretch it, flatten it, lean it, exaggerate it, or refine the broad shape until it fits your scene.

This makes Rock Shaper especially useful for set dressing and environment composition. You can create rocks that support a path, frame a vista, break up a terrain edge, form a landmark, fill awkward negative space, or match the visual rhythm of your level.

Presets are included as fast starting points, but they are not the limit of the tool. Rock Shaper is built for creating your own stylized rock variations quickly, without leaving Unity or sculpting every prop from scratch.

When the rock is ready, you can create it as a GameObject, save it as a reusable prefab with a proper mesh asset, add an optional Mesh Collider, or export the mesh as OBJ. FBX export is supported when Unity’s official FBX Exporter package is installed.

Rock Shaper is designed for stylized, low-poly, and faceted art styles. It focuses on mesh generation and shape control. It does not generate procedural textures or advanced rock materials.
