Fast voxel engine for Unity 6 & URP: build infinite, destructible worlds with 3D node terrain, caves, smooth surfaces, structural collapse, PBR and water. Full source included.Voxel Play 4 - The voxel engine for Unity 6 & URPBuild vast, infinite, fully destructible voxel worlds - and let players reshape every block of them. Voxel Play 4 is a fast, feature-complete voxel engine and toolkit rebuilt from the ground up for Unity 6 and the Universal Render Pipeline. Terrain, caves, water, sky, vegetation, physics, lighting, inventory and world interaction all come integrated in a single solution, backed by full C# and shader source code.Whether you are making a voxel-style sandbox, a stylized adventure, a procedural survival game or an editor world-building tool, Voxel Play 4 generates rich worlds on demand and gives you everything you need to build, sculpt and destroy them - down to individual microvoxels.▶ WHAT'S NEW IN VOXEL PLAY 4- 3D Terrain Graph: node-based volumetric terrain generation with real caves, overhangs and graph-driven water at any height- Smooth terrains and voxels (Surface Nets) - freely mix smooth and cubic surfaces in the same world, with per-voxel override to keep crisp edges- Structural Collapse system: voxels fall only when they lose support, with cable snapping, per-voxel support distance, debris control and build-mode collapse- Super Chunks: distant terrain LOD for huge Terrain3D worlds- Chunk Occlusion Culling: skips hidden chunks for fast caves, tunnels and enclosed areas- Anti-Tiling: stochastic sampling breaks visible texture repetition all the way into the distance- Biome Tinting: smooth surface color blending between biomes- PBR model shader with full surface maps (metallic, occlusion, height, smoothness) plus a texture-packing utility- Mesh clouds, buoyant smoke particles and light-emitting fire- Voxel Reactions: define what happens when two materials touch (e.g. lava + water turns to solid rock)- Advanced microvoxel workflow: greedy-meshed slabs, OBJ export, and copy & stamp of shape, tint and graffiti with the pick tool- Underwater screen effect and caustics on any camera - no character controller required- New Floating Islands demo: ruined castles, stone bridges and cliff-side waterfallsVoxel Play 4 leverages highly optimized code - GPU instancing, texture arrays, greedy meshing and multithreading - to render beautiful, vast worlds that stay fast even on modest hardware.*** CORE FEATURES ***The goal of Voxel Play is to be an easy to use yet powerful, extensible, rule-based voxel engine that fills the open spaces of your world while letting you edit any area you want.Template based- Works with Scriptable Objects to define worlds, biomes, voxels and models. Each definition is a set of generation rules plus textures and sounds.- Define any number of worlds, biomes, models and voxels in the Unity Editor, and model your world interactively at runtime using the same interface (everything you change is saved).Extensible- Comprehensive set of runtime events (e.g. OnChunkBeforeCreate, OnVoxelCollapse, OnVoxelReaction).- Custom terrain generators and pluggable detail/spawner generators.- Full C# and shader source code included; scripts ship as assembly definitions (VoxelPlay / VoxelPlay.Editor / VoxelPlay.Demos).Ready to use- 8 demo scenes including textures, sounds and predefined biomes and voxels you can drop into your project.Performance & robustness- Hidden face removal, greedy meshing, GPU instancing, chunk occlusion culling, pooling and cache-friendly data structures.- Multithreaded chunk generation and meshing.- 64-bit internals with support for worlds up to 1,000,000 m in size, plus origin shift for large-world precision.- Octree-based voxel & chunk culling; customizable chunk pool.- Automatic NavMesh generation and standard Unity collider support.- Fast ray-cast system.Voxels & interaction- Destructible environment with damage cracks, particles and per-type hit/destruction sounds.- MicroVoxels: add fine detail (2, 4, 8 or 16 subdivisions) or carve parts out of larger voxels.- Custom-shape voxels (half-blocks, slabs, stairs), native rotation, dynamic voxels and connected voxels/textures.- Texture variations, animated textures and a customizable in-shader outline effect.*** RENDERING ***- Smooth Lighting (light spread / voxelized global illumination) with adjustable AO strength.- PBR support: per-voxel normal, height, metallic, smoothness, occlusion, opacity and emission maps (Cook-Torrance BRDF); reflection probe support.- POM (Parallax Occlusion Mapping) via relief mapping.- Emission / glow effects, torches and point lights with flicker, GPU torch sparks and per-frame cost that scales with nearby lights.- Configurable Max Point Lights (8-128) and improved point-light culling and sorting.- Color-based, transparent, cutout, textured, vegetation and water rendering variants.- Standard and colored shadows. VR compatible (Multi-Pass, Single Pass Stereo and Single Pass Instanced).*** TERRAIN ***- 3D Terrain Graph for volumetric worlds (caves, overhangs, biomes, graph-driven water) plus the classic multi-step heightmap Graph Editor.- Procedural voxel terrain generated on demand, with infinite seed-based variations.- Geological Layers: global underground strata shared across all biomes.- Full biome support (grassland, desert, forest, rainforest, tundra, taiga, snow, beach, shrubland, bare) with customizable surface, underground, vegetation and shore voxels, plus biome tinting and blending.- Biome map explorer window, cave systems and building/village spawners.- Unity terrain / SpeedTree / vegetation converter - turn an existing terrain into a voxel scene in a couple of clicks.- Curved-world effect over infinite terrain.*** INTEGRATED WORLD EDITOR ***- Unity-terrain-style tools to interactively model, sculpt and paint the generated world directly in the SceneView, with undo/redo and a model-definition creation workflow.*** WATER ***- Voxelized water with no redundant face overlap and an advanced flooding system.- Procedural, variable-height water voxels with slope and flow animation.- Realistic waterline meniscus and a clean above/below-water transition.- Seamless air-to-underwater camera transition with caustics and volumetric underwater fog, working on any camera.*** VEGETATION & SKY ***- Animated voxel grass and trees per biome, with per-plant width variation and custom-prefab support.- Underground/ceiling vegetation for caves and floating islands.- Voxelized skybox, day/night cycle, stars and dawns, distance fog with sky blending.- Animated voxel clouds that cast shadows, plus the new Mesh Clouds style with smooth coverage and horizon reach.*** CHARACTER CONTROLLER ***- Sample First-Person and Third-Person controllers tuned for the voxel environment: walk/run, crouch, edge hanging/peeking, fly, swim & dive, and terrain-based footfalls.- Includes a fully animated Hero model sample from Dungeon Mason. Also works with your own controllers.*** UI, ITEMS & INVENTORY ***- On-screen console (F1), FPS counter, animated crosshair, selected-material thumbnail and pixel font.- Collect voxels, select active items and build voxels, objects and complex structures at runtime.- Interactive objects framework with events, plus dozens of sample voxel definitions including 20+ high-quality PBR examples.*** LOAD / SAVE ***- Load and save to file or memory buffers, with optimized file size and incremental region-based saving (includes microvoxel data).*** TOOLS ***- Door creation tool, texture voxelizer, tileable noise generators, multi-textured cube generator.- Qubicle model import (.qb / binary) into optimized voxel meshes.- OBJ export for models and voxels, and a surface-map texture packer.Note: Voxel Play 3 is now in maintenance mode, meaning it won't receive new features, only fixes.
