About Digger PRO – Voxel Terrain Sculpting – Unity Editor Tool & Plugin

Unity Voxel Terrain Sculpting and Cave Generator Tool

Digger PRO – Voxel Terrain Sculpting is an environment modification tool that enables real 3D terrain sculpting on native Unity terrains. Rather than replacing the engine's landscape architecture with a full voxel engine, the system integrates localized voxel editing directly into standard heightmaps. This design allows developers to carve volumetric hollows—including caves, overhangs, arches, and tunnels—while preserving normal terrain workflows.

Volumetric Editing and Generation Architecture

The core pipeline uses voxels only where geometry is altered, minimizing performance overhead. Powered by Unity Jobs, the Burst compiler, and Awaitables, computations run across background worker threads to support real-time in-game terrain deformation without frame rate drops. The Configurable Voxel Generation System allows developers to swap generation strategies via ScriptableObjects, leverage depth- and noise-based layering through the Advanced Generator, or extend behavior using the IVoxelGenerator API.

Sculpting controls support custom brushes, texture painting on generated cave meshes, undo/redo actions, mesh resolution adjustments, and automatic grass and detail removal. To ensure physical realism, an automatic cleanup system detects and removes floating, unsupported voxel clusters. Voxel destructibility can be toggled per voxel to mark areas as destructible or indestructible, while the ModificationResult API returns real-time voxel statistics following any edit.

Runtime Persistence and Environment Integration

Digger PRO enables runtime terrain modifications that persist across sessions. Edits automatically update mesh colliders, manage level-of-detail transitions, and regenerate AI NavMesh data dynamically. The system natively handles multi-terrain setups and interfaces with terrain tools such as Gaia, MapMagic, TerrainComposer, and PolyTerrain. Rendering is compatible with the Built-in Render Pipeline, URP 17, HDRP 17, and MicroSplat workflows.

Use Cases

• Suitable for survival and sandbox titles requiring real-time in-game digging, mining mechanics, and persistent runtime tunnels.
• Can support underground exploration games needing interconnected caves, arches, and overhangs integrated into native Unity terrains.
• Useful for dynamic combat environments utilizing the ModificationResult API to feed voxel destruction data into resource and building systems.
