I finished a narrated mitosis film built as an editable Houdini scene. The camera moves from a whole human cell into chromosomes and molecular machinery, then returns to the two daughter cells.

Claude helped build the scene through Python. I split the work into scene components, then used separate review passes to inspect renders and measurements before revising the setup. The useful part of this workflow was being able to change the underlying geometry and animation after each review.

Protein-structure data informed the close-ups. The motion is staged for scientific storytelling, with compressed timing and schematic components identified on screen; it is not a molecular-dynamics simulation. I recorded the narration myself, and Drew Berry’s WEHI work was a major inspiration.

I’d welcome feedback on the scale transitions and readability of the chromosome sequence.

I’m Radu Cius, the developer of Houdini AI Assistant. This video shows a mecha model built in Houdini with help from the assistant.

I’ve been exploring AI-assisted modeling for mechanical characters and sci-fi assets, and wanted to share this hard-surface modeling example with the community.

If you use Houdini for this kind of work, I’d love to hear your thoughts. Would you be interested in a breakdown of the prompts and the Houdini node setup behind this build?

If you’d like to check it out, search for “Houdini AI Assistant” on Gumroad.

I've been exploring how AI and machine learning can accelerate FX simulations in Houdini. 

The process involves generating simulation data, extracting key information, and training a machine learning model to learn the behavior of the simulation. The trained model is then integrated back into the workflow to help drive the simulation and potentially reduce computational cost and iteration time.

The goal is to explore how AI can become an active part of the simulation process, rather than being limited to prediction or post-processing.

This is an ongoing R&D experiment focused on making complex FX workflows more efficient.

One Houdini node that builds a human body in real units (age in years, height in cm, weight in kg) and animates it from a sentence.

- Body: open-source SOMA and Anny body models, solved to hit the exact height and weight

- Shape: gender, muscle, breasts, buttocks, surface smoothing

- Motion: NVIDIA Kimodo text-to-motion, running locally on my GPU

- Path: draw a curve, and Kimodo generates the motion on it

The repo is live but reddit seems to be blocking it if I try to post a link here. You can find it on my Instagram @ devanshutak25 (the link to that is also in my bio here on reddit)

I created a version of Cycles render engine for Houdini using the hdCycles branch by Christopher Hosken(cjhosken/hdCycles) and Claude. It is super responsive! Some of the features don't work at the moment but still this is promising! Really excited to finish it and then use it on an actual production!

Will be opensourcing it as soon as volume rendering starts working!

Is there a viable MCP for Houdini? By "viable" I mean, acceptable for commercial use in pipeline projects?

Just an ethical disclaimer since this is an early post on this sub: AI is a tool. It's just a hammer, and not every problem is a nail. It's everyone's prerogative as to what constitutes a nail.

To me, as an artist, it's along the lines of never using AI for things I can't do by hand. And, recognizing AI is categorically incapable of human creativity.

So what's left? Houdini is sometimes tedious to use, and writing python or hscript is not a particularly creative process. Neither is integrating Houdini into a complex pipeline. That's just work you do in service of Art.

Anyway...

Hey everyone! I’m FX TD, one of the founding moderators of r/AiForHoudini.

Welcome to our new home for everything related to AI + Houdini!

The idea behind this community is simple: share what you’re actually creating with AI in Houdini. Whether it’s a cool simulation, VEX setup, Python tool, HDA, procedural workflow, experiment, render, or something completely weird—we want to see it.

What to Post

Share anything related to using AI with Houdini:

• Houdini projects created with AI
• VEX and Python experiments
• AI-assisted simulations and procedural setups
• Tools, HDAs, and workflows
• Renders, breakdowns, and experiments
• Questions, discoveries, failures, and useful tips

Basically, if AI helped you make something in Houdini, post it.

Community Vibe

Keep things friendly, constructive, and welcoming. You don't need to be an expert to participate. Show your work, ask questions, share what you learned, and help others when you can.

And yes—using AI does not automatically make your post spam here. 😂

If you made something cool with AI + Houdini, share it! We want to see what people are actually building.

How to Get Started

1. Introduce yourself in the comments.
2. Share something you’ve made with AI + Houdini.
3. Ask a question or start a discussion.
4. Invite other Houdini artists who might be interested.
5. Want to help build the community? Reach out if you’re interested in becoming a moderator.

Thanks for being here from the very beginning.

Let’s see what the Houdini + AI community can build together.

Welcome to r/AiForHoudini!

Excited to announce Qwen3-8B-Houdini-VEX
100% LOCAL & PRIVATE — Runs on GPUs with just 10GB+ VRAM. No cloud, no API, no data leaving your machine.

This is my second LLM fine-tuning experiment focused specifically on Houdini VEX, building on what I learned from the first version and pushing it further.
