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.

My goal with this tool isn't to replace that creative part that's the fun! It's to automate the boring part, like debugging a simple VEX typo at 2 AM.

The idea is to free up more time for the interesting setup work that you're talking about.

And absolutely, it's perfect for learners too! They can select a network or node they don't understand, hit 'Analyze Selection', and then simply ask: "What does this network do?" or "Explain this node in the context of the selection." The assistant, using the 'Scene Analyst' role (and maybe even the 'Explanatory' style), will provide a detailed, step-by-step explanation.

Hi, one thing I’m exploring deeply right now is this:
How far can AI go inside Houdini when it actually understands the procedural context?



I just made a new demo where HDA Architect in Houdini AI Assistant generates a procedural Asteroid Generator from a prompt.

What I like most is not just the speed, but the fact that I can inspect the generated network, adjust it, disable weak parts, refine the logic, and continue building from there.




For me, that’s the interesting part AI not as a replacement for procedural thinking, but as a serious accelerator for it.

Huge thanks to everyone sending feedback, testing the tool, and helping me improve it.

Houdini AI Assistant v0.1.6 AI-generated HDA, MaterialX, Solaris/Karma, Pyro, FLIP and RBD networks
Demo video:

Hi everyone,
I wanted to share a new demo of Houdini AI Assistant v0.1.6, a tool I’ve been developing to bring AI assistance directly inside Houdini.




The basic workflow is:
Prompt → Generate Network → Inspect → Refine

In this demo I tested several Houdini workflows:
* HDA Architect for procedural sci-fi assets
* MaterialX shader generation
* USD asset import inside Solaris
* Solaris / Karma render setups
* Pyro networks
* FLIP simulations
* RBD destruction setups
* Animation Maker for text-guided character motion

The generated networks are meant to be starting points, not final black-box results. The goal is to create editable Houdini node networks that can be inspected, modified, debugged, and improved manually.

For example, in the demo I show:
* prompt-generated procedural HDA assets, including a sci-fi hangar and freighter ship blockout
* MaterialX / Karma shader networks generated from prompts
* Pyro smoke/flame setup
* FLIP water simulation setups
* RBD destruction setup
* Solaris/Karma render and material workflows



For production-quality results, manual refinement is still required especially for simulation resolution, constraints, collisions, caching, meshing, surfacing, shader cleanup, timing, and art direction.
Most examples in this demo were generated using GPT-5.5 / GPT-5.4, with some manual adjustment or error correction where needed.
For best results with HDA Architect, I currently recommend using the latest GPT models, especially for more complex Houdini setups. Local models can be useful for lighter tasks such as scene analysis, node explanations, and general Houdini help, but they are not reliable enough yet for complex HDA Architect network generation.

System requirements:
* Houdini 20.0, 20.5, 21.0
* Windows, macOS, Linux
* Animation Maker is currently available only in the Windows build
