Mogen Studio

MoGen is a procedural 3D model generator. It turns a compact, declarative DSL into game-ready glTF 2.0 (.glb) assets — and an LLM can write that DSL for you from a plain-text prompt.

MoGen Studio is the desktop app: a DSL editor with a live 3D preview, validation diagnostics, and one-click generate / modify / animate calls to your chosen LLM. The same deterministic pipeline also ships as a command-line tool.

Why a DSL? LLMs are good at structure and intent, bad at floating-point geometry. The language model decides what to build — the parts, their roles, how they relate — while deterministic Rust code handles how to build it. Small outputs, cheap iteration, no hallucinated triangles.

What it does:

• Primitives, CSG (union / difference / intersect), hierarchy and reusable modules
• Arrays, mirrors, oriented connectors and an attach solver
• Skeletons, skinning and procedural animation templates
• Full PBR materials with embedded, generated textures
• Watertight, spec-compliant glTF for Godot, Blender, three.js and anything that reads glTF 2.0
• Multiple LLM backends: Gemini, OpenAI, Anthropic, Ollama (local), Claude Code, Fireworks and Z.ai

Built in Rust. No runtime, no graph editor, no engine lock-in — just a parser, a scene graph, a mesh library and a glTF exporter.
