raducius Posted October 23, 2025 Share Posted October 23, 2025 (edited) Stop Fighting with Networks. Start Creating. Analyze. Debug. Generate. Automate. Houdini is powerful, but endless debugging and reverse-engineering complex networks can kill creativity and waste hours. Houdini AI Assistant is a native tool that solves this problem. It’s not just another chatbot. It’s your personal Assistant that reads your scene, nodes, and parameters to give you answers that are actually relevant to your project. Demo video: More info: https://rart.gumroad.com/l/HoudiniAIAssistant It reads your scene (nodes, parms, context) and gives answers that are actually relevant to your graph. This AI can actually run code in Houdini. 1. Can this tool create nodes for you? Yes, absolutely. It has two main features for this: Recipe Builder: If you ask the AI, "How do I make a mountain?", it can provide an answer that includes a special RECIPE: tag (e.g., RECIPE: grid -> mountain -> null). The chat window detects this and will automatically show a "Build Network" button. Clicking this instantly builds that exact node chain in your current network editor. HDA Architect(Beta): There is a dedicated "HDA Architect" Beta feature. You can give it a prompt like, "Build an HDA for a line with 'Length' and 'Points' parameters." The AI builds the internal nodes, and promotes and re-labels the parameters exactly as you specified. 2. Can it modify scripts? Yes, it can. The AI has a "VEX/Python Programmer" role. You can ask it to write any hou Python script, including scripts to modify HDA definitions. The AI is instructed to wrap simple, executable scripts in special tags (ACTION_PYTHON ... END_ACTION). When the tool sees these tags, a "Execute Action" button appears in the chat.

raducius Posted February 22 Author Share Posted February 22 What’s New in the Houdini AI Assistant v0.1.5 Multi-provider AI support: OpenAI (GPT) Anthropic (Claude) DeepSeek Houdini AI Assistant: https://rart.gumroad.com/l/HoudiniAIAssistant Local AI support: run models locally via LM Studio or Ollama (great for privacy/offline workflows). Prompt editing: you can now edit in the UI. MoE for HDA Architect: a Mixture-of-Experts workflow to improve HDA generation quality and consistency. Thinking level controls: select the thinking level for both Scene Analyst and HDA Architect. Easier installation: smoother setup with clearer guidance and fewer manual steps. Improved international input (Qt6 only for now): better support for Japanese, Chinese, and Korean text input. Qt5 support is coming later.

raducius Posted 3 hours ago Author Share Posted 3 hours ago What if you could turn a simple prompt into a working Houdini HDA? In this demo, I use Houdini AI Assistant to generate a procedural Asteroid Generator in minutes. Houdini AI Assistant: https://rart.gumroad.com/l/HoudiniAIAssistant Instead of spending hours building node networks from scratch, the assistant helps speed up the process by generating the structure, parameters, and procedural logic from a prompt. In this video, I show: Prompt to HDA workflow AI-generated procedural asteroid setup Node-by-node inspection of the generated network Parameter tweaks and improvements Final result after just a few minutes This is not just a generic chatbot. Houdini AI Assistant works inside Houdini and helps with analyzing, debugging, generating, and automating procedural workflows. If you are learning Houdini, building tools, or trying to move faster in production, this is exactly the kind of workflow that can save a huge amount of time. Try Houdini AI Assistant here: https://rart.gumroad.com/l/HoudiniAIAssistant Thank you for all the support and feedback it really helps me improve the tool. More updates and demos are coming soon. 1 Quote Link to comment Share on other sites More sharing options...
