It's a bit hard to say "I made this", but I guess that's where things are going

It's of course just a tiny corner of its big brother, but still wild how far these things have gone in just months.

"Houdini in 10 hours"

Shit is getting wild. I was waiting for our car to get fixed, and downloaded VSCode and Codex. 10 hours later I have a Houdini-esque node-based geometry editor running.

Oh I guess it was this already? watched too fast the first time

Quarter-Tile Autotiling Since Oskar posted about it, I see an increasing amount of praise for his Dual Grid proposal for autotiling terrains. It works by drawing tiles at a half-cell offset to the base grid, creating a du…

Oskar Stålberg on X: "More talk prep. Gonna have another go at persuading people to cut their tiles along the dual grid instead of the main grid. I genuinely don't understand if this is rare because people don't know about it or if there is some drawback I'm not seeing. https://t.co/nm4aDLAesT" / X More talk prep.

I had a presentation on our Pax Dei world generation pipeline at the Everything Procedural Conference last April.

If you're interested in large scale game world generation, procedural techniques, #Houdini and #Unreal, take a look!

Of course had to port it for Houdini dailyhip.wordpress.com/2025/07/23/e...

Super cool! I just had to port it to Houdini as well :)

It does not always result in working code, but at least you can quickly get something to improve on.
This uses ChatGPT 4o, and there is a hidden parameter where you should put your OpenAI API key.
(I put in a default key with 20€, so with some luck you can test it without one:)

Thinking of how to combine LLMs with
@sidefx.bsky.social #Houdini

Here's LLM-enabled variants for Attribute Wrangle SOP and Python SOP.
The difference is a string input where you can describe what you want the Wrangle to do, and it will initialize the code field

This MCP stuff is cool so I had to make a Houdini-MCP as well. Mostly a conversion of
siddharth ahuja's Blender-MCP, but with the addition of Claude being able to get an OpenGL render - to enable it to see what it's doing. Not useful for real, but a fun gimmick and maybe a sign of things to come.

I first tried with a local Deepseek-r1:32b, but kept getting errors with 85% of even the simplest wishes. GPT-4o makes valid code maybe a bit over 50% of the time. With a niche API like HOM these model just keep hallucinating. Would need to finetune with Houdini documentation and examples?

Don't worry, our jobs are safe, this can't really do anything of actual use.

A bit of LLM fun in @sidefx.bsky.social Houdini, less than one cent a wish! ;)

Pax Dei’s chat system is now powered by Discord | Pax Dei - Social Sandbox MMO A social sandbox MMO developed on Unreal 5, where you can build a home, craft your weapons and go to war. What world will you make?

As far as I know we are first to integrate Discord into our game. Our in-game chats are now actually Discord chats, and you can message between Discord clients and the game.
The initial implementation is quite barebones, but this opens up a lot of possibilities! playpaxdei.com/en-us/news/g...
