Track Zero

A Zig/Vulkan driving sandbox and in-world terrain editor.

The project is focused on cars, procedural terrain, construction, roads, and collaborative world editing. It contains no enemies, creatures, NPC AI, weapons, shooting, combat, or invasion mode.

Features

• Box3D-powered cars with suspension, gears, wheel input, and force feedback
• Procedural terrain, roads, rocks, water, tunnels, and authored structures
• In-world editor for terrain, materials, objects, roads, pipes, construction, and car playtests
• Vulkan 1.3 renderer with ray-traced shadows, SSGI, volumetrics, and GPU-driven scene culling
• Optional eight-player car/editor relay with shared patch leases
• Data cartridge packaging for assets and shaders

Build

Requirements: Zig 0.16, Vulkan 1.3 ray-query support, and the vendored dependencies in deps/.

zig build            # retail package
zig build run        # build and run
zig build test       # client, game, protocol, relay, and editor tests
zig build server     # headless multiplayer/editor relay

See BUILDING.md for platform setup and packaging details.
