Kiln

Kiln is an open-source procedural 3D engine and toolchain designed for AI-driven asset prototyping in game development. It enables language models to write and revise JavaScript programs that generate editable, game-ready GLB 3D assets. Kiln includes a local runtime, CLI, TypeScript library, and MCP server to render, inspect, and export 3D models with version control, focusing on organized iterative editing rather than one-shot mesh generation.
