Description
Next week update to 5.8
The ultimate, fully procedural geological generation tool for Unreal Engine 5. Generate, iterate, and bake infinite, Nanite-ready rock formations directly in your Editor.
⛰️ Limitless Geology at Your Fingertips
Stop manually sculpting rocks and placing individual assets. Procedural Rocks Generator is a powerful, C++ driven plugin that allows you to instantly spawn highly detailed cliffs, boulders, desert pillars, and crystal formations with a single click. Every rock is generated dynamically in-engine, giving you an infinite library of unique assets without inflating your project's disk size.
🚀 Built for Nanite & Unreal Engine 5
This is not a traditional low-poly generator. Our custom mesh builder natively supports Nanite workflows. Push your procedural meshes up to 1.5 Million Triangles for breathtaking cinematic quality, and use the built-in Bake to Static Mesh feature to permanently save your creation as an optimized, Nanite-ready .uasset with perfectly calculated explicit tangents.
🛠️ Unmatched Customization
Drive your environment storytelling using a massive suite of parameters. Control cellular faceting, high-frequency roughness, thermal weathering, and gravity-biased sediment erosion. Want to base your rock on an existing blockout? Use the Custom Mesh Base feature to wrap procedural algorithms around your own models!
🔥 Key Features & Capabilities
Infinite Variations (1-Click Randomize): Found a style you like? Click Randomize Seed to instantly generate an endless stream of unique variations.
Dynamic Optimization Profiles: Seamlessly switch between Preview Quality (for fast blocking), Game Asset (optimized balance), and Cinematic Quality (extreme high-resolution meshing).
Spline-Based Generation: Draw custom cave walls, winding canyon borders, or cliff faces effortlessly using Unreal’s native Spline Components.
Scatter & Debris System: Generate chaotic gravel beds, river stones, or magical crystal clusters in seconds using the Scatter generation mode.
CPU & Shader Displacement: Full support for both built-in geometric CPU Displacement (guaranteed watertight meshes) and Material-based Nanite Tessellation (Shader Displacement).
Micro-Displacement Support: Blend secondary high-frequency detail maps for extreme macro shots without losing underlying rock structure.
📦 What’s Included in the Plugin?
Procedural Rocks Generator creates rock meshes inside Unreal Engine without requiring an external DCC tool. You place a generator actor in a level, choose a preset, adjust settings and bake the result to a Static Mesh when you are happy with the shape.
You can create:
Small stones and river rocks.
Medium boulders and boulder clusters.
Modular cliff pieces for level building.
Jagged broken cliffs and sharp stone shards.
Desert pillars, hoodoo stacks and balanced rock formations.
Basalt-like columns and volcanic shapes.
Long spline-based canyon walls and rock tubes.
Custom-mesh-driven rocks using your own Static Mesh as the starting shape.
High-detail hero rocks with main displacement and micro displacement.
The plugin includes:
ProceduralRockGeneratorActor, the main actor used to generate rocks.
Built-in procedural presets.
Demo maps.
Master materials, material instances and material functions.
4K texture sets, normal maps, roughness maps, displacement maps and micro-displacement maps.
Example baked Static Mesh assets.
Editor baking tools.
🎯 Who is this for?
Whether you are an Indie Dev building a massive open world, a Level Designer needing custom canyon walls that perfectly fit your gameplay paths, or a Cinematic Artist requiring ultra-detailed hero boulders—Procedural Rocks Generator eliminates the need for external sculpting software.
Create. Bake. Build your world.
Requires Unreal Engine built-in ProceduralMeshComponent plugin.
Supported target platform: Win64. Supported Unreal Engine version: 5.7.
Includes Runtime module: ProceduralRocks. Includes Editor module: ProceduralRocksEditor.
Built-in Unreal Engine plugin: ProceduralMeshComponent.
Recommended:
Nanite enabled in your project if you want dense baked hero rocks.
Lumen or another dynamic lighting workflow if you do not want to generate lightmap UVs for very dense meshes.
A reasonably modern CPU for Hero and Cinematic generation.
Optional:
Nanite tessellation project settings or console variables if you use the optional Create Nanite Displacement Material feature. This is a material/GPU visual feature and does not change collision.
