Aerial overview of a complete generated voxel diorama with lakes, cliffs, and scattered trees

Generate and sculpt a voxel diorama, then hop in and walk it: sprint, double-jump, slide, swim. Day-night, weather, wildlife. Traversal hotbar unlocked from the start: jetpack, glider, rocket boots, grapple, balloon, lantern; plus a gravity dial. Export the terrain into your own s&box games. Friends join from the same seed and spec: co-op without streaming geometry.

Explore what you built

Hop into a character and walk the diorama: run, sprint, double-jump terraces, slide slopes, swim lakes. Day-night, weather, wildlife per biome. Prefer to fly? Toggle noclip and soar.

/02
Traversal kit, unlocked

Hotbar of gadgets from the start: jetpack (thrust + boost, refuel on ground), glider, rocket boots, grapple, balloon, lantern. Gravity dial bends the kit from moon-jumps to heavy boots.

/03
Slider-driven worlds

Seed, sea level, amplitude, biomes, rivers, roads. Regenerate a dense voxel diorama from a WorldSpec, not a hand-built scene.

/04
Brush, then play

Raise, lower, flatten, paint. Then run the character through the terrain you just shaped: greybox that is already a game.

/05
Invite friends in

Launch a server, share a short invite code. Peers regenerate the same world from the spec: co-op without streaming geometry.

/06
Export into your own games

Bake the terrain into chunk models another s&box project can load. Generate and sculpt here, then drop the world into your own game.
