Help, I'm using Houdini
This is a submission for the Hacktoberfest Open-Source AI Challenge: Week 3 — Slow and Steady If you've ever used Houdini for VFX, Procedural modelling, animation or CG content creation then you're probably familiar with its help-browser. Houdini's help-browser is a very useful source of documentation for any user looking for more information about all parts of Houdini. However, It is not…
The Hacktoberfest Open-Source AI Challenge - Week 3 project, "houdini-wizard," is a shelf tool designed to enhance the user experience when working with Houdini's procedural modeling, animation, and CG content creation capabilities. The tool is built on top of Houdini's existing help-browser but adds several features that set it apart from the standard documentation viewer.
One key feature of houdini-wizard is its ability to update the help documentation in real-time as the user selects different nodes in the node network viewer. This ensures that the displayed information is always relevant to the currently active node, making it easier for users to understand the node's functionality and how it fits into their overall scene.
In addition to updating the help content dynamically, houdini-wizard also provides valuable insights into the node's input and output connections, giving users a clearer picture of how the node interacts with other elements in their scene. The tool also incorporates Houdini's existing parameter organization and enriches parameter documentation by including tooltips directly in the help panel, combining the best aspects of both the traditional help-browser and a more interactive documentation system.
To further improve the user experience, houdini-wizard maintains existing UI helper-text that users can access on-hover of parameter settings, ensuring a seamless transition between the native Houdini interface and the enhanced help functionality provided by the tool. The repository for this project can be found on GitHub at AbisoyeOnanuga/houdini-wizard, where users can explore the full documentation library by category and open the tool without selecting a node to browse the entire help library.
The development of houdini-wizard involved several key components, including Houdini Python and PySide for interacting with the user's active node, the live input and output wires, and parameter tabs; the local installation of Houdini Help files located at $HFS/houdini/help, which contain the source documentation for each node; and the use of Gemma 3.4B, a locally-hosted AI model hosted via Ollama, to provide additional context and explanations when needed.
The AI model is guided by strict skill prompts to ensure it only returns existing help headings or provides concise, single-sentence explanations based on the actual values present on the parameter's slider. This approach prevents the model from inventing settings or attempting to art-direct the user's scene, maintaining the integrity of the documentation while still offering valuable insights.
The project employs a multi-process agent harness, where the AI model selects the appropriate tool for each scenario, allowing for a smooth and efficient workflow within the Houdini environment. The entire development process is tracked and documented through a Python SDK, enabling users to query the reasoning behind specific guardrails and modifications made to the tool.
By combining the power of Houdini's built-in documentation with the contextual understanding of an AI model, houdini-wizard offers a more intuitive and informative way for users to explore and utilize the full potential of Houdini's capabilities. The project demonstrates the potential for AI to enhance existing tools and workflows, ultimately improving the user experience and streamlining the creative process for artists and technicians working with Houdini.
