## What it is
ProtonGraph is a standalone, node-based desktop application for procedural 3D content generation, built as a Godot engine project. Users chain simple nodes into graphs to produce complex 3D models, functioning like visual scripting specialized for game asset creation.

## Use cases
- generate 3d models procedurally with a node graph
- node-based procedural content generation tool for games
- create game assets like props and terrain without manual modeling
- visual scripting for 3d mesh generation
- free open-source alternative to houdini or blender geometry nodes
- generate content on the fly inside a godot game
- scatter, deform, and combine meshes using nodes

## When to choose
- You want a free, MIT-licensed, node-based tool for procedural 3D content centered on game development
- You work in the Godot ecosystem and want to embed or extend procedural generation without legal headaches
- You prefer a lightweight standalone app over learning Houdini or Blender Geometry Nodes for simpler procedural assets

## When to avoid
- You need production-stable, feature-complete procedural modeling - the project is explicitly experimental and mid-port to Godot 4 with some missing or broken features
- You need a full Houdini or Blender Geometry Nodes replacement for film-grade VFX or complex pipelines
- You need runtime in-game content generation today - that is a long-term goal, not a current capability
