NodeArchitect is an AI agent and MCP server for Houdini that reads your live node graph, parameters, and connections. Ask it to explain a network, debug an error, write VEX/Python, or build an HDA — grounded in your actual scene, not guesses. v2.3.1 adds ChatGPT/Codex login, Plan Mode, HDA Composer and Copernicus support. v2.4.0 adds Houdini 22 support.

I was looking for an AI tool to help with my Houdini projects, but what I found was priced out of reach for me. So I built NodeArchitect, an AI agent designed specifically for Houdini. It’s free for non-commercial use, so new artists can use it without barriers. NodeArchitect is a Houdini plugin that gives you an AI Agent that actually understands your scene. It doesn’t just respond with generic advice, it reads your node graph, interprets context, and works directly with what you’ve built.
