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
