Rock And Rock Wall Generator Kit

Procedural rock and modular stone wall generator for Unity featuring in-editor randomization, overlap removal, LOD baking, and NavMesh support.

Technical Details

Package Specifications:

• File Format: Unity Package (.unitypackage)
• Target Render Pipeline: Universal Render Pipeline (URP)
• Unity Version Support: Unity 6.0 or later (verified); Unity 2022.2+ (URP 14+) may be compatible but is not officially tested
• SRP Compatibility: Fully compatible with Universal Render Pipeline (URP); SRP Batcher supported
• Pipeline Restrictions: Forward / Forward+ rendering paths only; not compatible with HDRP or Built-in Render Pipeline
• Shader & Feature Limitations: Does not support static lightmap baking or Unity 6 GPU Resident Drawer

Procedural Tool & Level Design Utilities:

• Generator Modules: Procedural Rock Generator, Procedural Rock Wall Generator
• Baking Engine: One-click static mesh baker with automatic hidden geometry removal
• LOD Management: Automatic LOD group generation supported during bake
• Collision & Navigation: Automated primitive/mesh collider setup and NavMesh obstacle carving supported during the baking pipeline
• Editor Gizmos: Real-time visualizers for polycount bounds, pivot points, collider limits, and NavMesh carving areas

Asset & Geometry Details:

• Included Base Meshes: 15 modular rock and boulder base models
• Polygon Count (Base & Baked Meshes): Individual Rocks & Boulders: 250 – 1,200 triangles per mesh; Modular Rock Walls: 1,500 – 4,200 triangles per section. 
• Note: Procedurally generated meshes scale polygon count dynamically based on user subdivision/detail settings.
• Procedural Variations: Infinite (procedural seed, proportion sliders, shape styles, and custom mesh inputs)
• UV Mapping: Yes, clean unwrapped UVs with tiling and texture atlas support
• Colliders: Supported (configurable via tool settings)
• LODs: Supported (auto-generated on baked assets)

Materials & Textures:

• Material Workflow: Stylized / PBR
• Texture Resolutions: Individual palette swatches and texture maps at 32×32 px
• Texture Formats: PNG / TGA (Lossless)

Features:

• Procedural Rock Generation: Seed-based randomization, Cubic/Crystal styles, and custom mesh support

• Procedural Rock Wall Builder: Scatter mode, modular prefab tiling, grid layout controls, and chaos/jitter offsets

• Optimization & Baking Engine: One-click static mesh baking, internal overlap removal, and automatic LOD generation

• Scene Visualization & Gizmos: Real-time preview of performance bounds, center pivots, collider shapes, and NavMesh carving

• Level Design Workflow Utilities: Global batch tracker to select, wipe, or hot-swap baked rock assets across scenes

Supported OS:

• Check Windows (Unity Editor) (Note: If the portal has checkboxes, you can safely check macOS and Linux as well, since Unity C# Editor scripts without native .dll plugins run cross-platform on all desktop editors).

Rock & Rock Wall Generator Kit + Procedural Level Tools

Streamline your environment art and world building with this intuitive procedural generation toolkit for Unity. Effortlessly generate endless variations of organic rocks, boulders, and modular stone walls directly inside the Unity Editor. Featuring real-time parameter tweaking, automated mesh baking, hidden geometry cleanup, and LOD generation, this tool empowers level designers and environment artists to build optimized rocky landscapes in seconds.

◼ Procedural Rock Generator

• Seed-Based Randomization: Generate infinite unique rock shapes instantly using randomized seed values or manual inputs.
• Distinct Shape Styles: Choose between organic, Cubic, and Crystal stylized rock silhouettes to match your project's aesthetic.
• Fine-Tuned Geometry Controls: Dial in density, radius, wave deformation, surface asymmetry, and decentralization.
• Proportion Shaping: Tailor assets to fit level slots with dedicated tallness, flatness, and wideness scaling sliders.
• Custom Base Mesh Support: Feed your own custom 3D meshes into the generator to use them as procedural modular building blocks.

◼ Procedural Rock Wall Generator

• Modular Wall Chunks: Assemble modular stone walls, cliff barriers, and defensive boundaries with adjustable grid density and dimensions.
• Organic Randomization: Break up repetitive patterns using automatic position offsets, rotational jitter, and scale variation.
• Seamless Tiling: Create repeatable modular wall prefabs designed to snap together and build expansive fortifications or canyon corridors quickly.

◼ One-Click Baking & Production Optimization

• Static Mesh Baking: Convert dynamic procedural structures into lightweight, standalone Unity static meshes with a single click.
• Automatic Overlap Removal: Cleanly strip hidden internal faces and overlapping polygons during bake to keep polycounts minimal and avoid overdraw.
• LOD Generation: Automatically create production-ready Level of Detail (LOD) groups for smooth frame rates across varying view distances.
• Colliders & NavMesh Setup: Configure automated primitive/mesh colliders and NavMesh obstacles directly in the baking pipeline.

◼ Scene Visualization & Level Design Utilities

• Real-Time Viewport Gizmos: Preview performance bounds, center pivots, collision boundaries, and NavMesh carving regions right in the Scene view before baking.
• Batch Scene Operations: Quickly select, delete, or replace all baked rocks and wall segments across your scene.
• Asset Swapping: Swap early prototype whitebox rocks with final optimized prefabs without losing level layout placement.

◼ Package Asset Manifest

Procedural Editor Tools & Scripts:

• Procedural Rock Generator Editor Window & Utility Scripts
• Rock Wall Generator Editor Window & Grid Placement Tools
• Mesh Optimization, Hidden Face Stripping & LOD Baking Modules

Included 3D Assets & Presets:

• 15 Ready-to-use hand-crafted base rock & boulder prefabs
• Pre-configured generator presets (Cubic, Crystal, Smooth Boulder, and Modular Wall Chunks)
• Demo scene showcasing active generator setups, baked comparisons, and performance visualization gizmos

(Note: Architectural ruin structures, trees, and custom nature foliage shaders are not included in this standalone toolkit; they are available in their respective kits or together in the master Ultimate Overgrown Ancient Ruins Pack).
