Voxel Terrain – Dig & Build Destructible Low Poly Worlds

Dig anywhere. Build anything. A lightweight, Astroneer-style destructible

terrain system with a stylized flat-shaded look — drop one component into a

scene, press Play, and carve caves with your mouse. Full C# source included.

TERRAFORM WITH 2 LINES OF CODE

• VoxelModifier.Dig(point, radius) — carve smooth spheres out of the world

• VoxelModifier.Build(point, radius, biome) — add matter in any of the 7

  biome materials

• Strength overloads for gradual, hold-the-button sculpting

• That's the whole integration. No setup, no baking, no plugins.

STYLIZED LOW POLY LOOK

• Marching-cubes surface with TRUE flat shading — crisp faceted terrain,

  not smoothed blobs

• 7 vertex-colored biomes: grass, dirt, stone, sand, snow, purple ore and

  cyan crystal — recolor everything from one palette in the Inspector

• Dig down and the exposed material changes naturally: grass to dirt to

  stone, with ore pockets and crystal veins waiting deep underground

• Includes a vertex-color shader that works in URP AND Built-in from a

  single file — plus caves, cliffs and overhangs out of the box

FAST WHERE IT MATTERS

• Chunked world — only chunks you actually modify are re-meshed

• MeshColliders bake on a BACKGROUND THREAD: digging never stutters the

  main thread (measured: a full 96x48x96 world generates in ~150 ms)

• Everything is plain C# and one material — no compute shaders, no GPU

  requirements, mobile-friendly

PLAYABLE DEMO IN ONE CLICK

• Tools > Abduo Bricks > Voxel Terrain > Build Demo Scene creates the

  materials, the mining-gun prefab and a ready demo — on URP it even adds

  a post-processing volume (ACES, bloom, vignette) for the showcase look

• Fly around with a first-person mining gun: left-click digs, right-click

  builds, mouse wheel resizes the brush, on-screen UI picks the biome

• Works with BOTH input backends automatically (classic Input Manager and

  the new Input System) — no .inputactions setup

INCLUDED CONTENT

• Complete voxel engine source (worlds, chunks, noise, biomes, caves, ore)

• 5 low-poly FBX props with vertex colors: conifer, oak, rock cluster,

  glowing crystal ore, sci-fi mining tool

• Prop scattering that reacts to terrain: trees spawn on grass, digging

  under a tree knocks it out of the world

• Demo scene, mining gun controller, self-building demo UI, quick-start

  guide — every Inspector field has a tooltip
