Kiln

Kiln is a local text-to-3D engine where a coding agent (Claude Code, Codex, OpenCode, Cursor and others) writes small JavaScript programs using Kiln's geometry and material helpers, renders them, inspects the views and structural checks, and revises until the asset is right. It ships as an MCP server, a CLI and a TypeScript library, and exports game-ready GLBs while keeping the editable source so parts, dimensions and variants can be changed later. A solo maker would use it to get props, vehicles, machinery, buildings and rigid-part animations into Blender, Unity, Godot or three.js without modelling by hand; organic characters are explicitly a weak spot.
