Folks. Can I explain something about world models? Seems like today might be a good day for that. Advances in large-scale “world models” — whether developed by partners like Google or others — materially expand the frontier of interactive content creation. These models can generate high-quality, interactive, video-like experiences from natural language or minimal input. Today, they are primarily editable through prompting, which limits the level of determinism and precision required for production-grade game mechanics. As a result, their outputs remain probabilistic and non-deterministic, making them unsuitable on their own for games that require consistent, repeatable player experiences. Rather than viewing this as a risk, we see it as a powerful accelerator. Video-based generation is exactly the type of input our Agentic AI workflows are designed to leverage—translating rich visual output into initial game scenes that can then be refined with the deterministic systems Unity developers use today. Our agents already generate high-quality scenes from static video. Interactive, camera-controllable video from world models would further enhance this pipeline and materially improve the fidelity and speed of early-stage content creation. We believe this represents a meaningful step forward for AI-driven development across the industry. Unity’s role is to operationalize these advances. Outputs from world models are ingested into Unity’s real-time engine, where they are converted into structured, deterministic, and fully controllable simulations. Within Unity, creators define physics, gameplay logic, networking, monetization, and live-operations systems to ensure consistent behavior across devices and sessions. This combination enables developers to move faster from concept to scalable product: AI accelerates environment and asset generation, while Unity provides the execution layer that transforms generated content into reliable, monetizable experiences. As a result, world models expand content supply and reduce development friction, while Unity remains the system of record for runtime, distribution, and long-term operations. This dynamic broadens Unity’s addressable market and reinforces its central role in the interactive ecosystem.

Congrats @TeamCherryGames on the incredible journey to Silksong! Creating a giant game with a small team takes powerful tools, and we’re proud to help bring your vision to life across platforms. #MadeWithUnity #Silksong

Finally deleted the X and Facebook apps from my phone. The clincher was their refusal to let me open links in the system browser.

@RouaniJihad Ah, that one I think is coming in 2025 indeed :)

@Superpig oh, I just remembered something on topic, can we get Unity documentation in Dark mode? That would be cool as we spend soooo much time reading them, a feature to help the eyes has a big impact on the experience. I made a concept about it a while ago:

We recently spent a week jamming on the #Unity API documentation. I wrote a little report about it: discussions.unity.com/t/api-docs-qua…

@RouaniJihad I would not call 39,000+ symbols “a lack of extensive API” :) It might be missing specific things that you want, but that’s a separate problem!

@Superpig The blog post seem to be about the clarity of API doc, but there's a deeper problem in Unity, a lack of extensive API in the first place, there are so many things we need that are not exposed like: 1- Light position from lights created by particles. 2- Motion vector pass in URP..

🤔?

@Cmdr_Hadfield Bonjour-hi :)

Like a time portal - la belle ville de Montréal en automne.

Enjoying #unity6 ? I had the pleasure of creating its key art visual — using Unity 6, of course!

First Time Ghost scenes released! ✨ We’ve just published two projects: showcasing the character and the grassy environment scene. Have a look at the hair simulation…

It's here. #Unity6

Today @Unity 6 releases . Our '6 Hours of Unity 6' livestream kicks off in about an hour at 8a PT/11aET/1500 UTC. I kick off the stream followed by product team interviews. Drop by, say hi and learn about the latest release. on.unity.com/3BWpY2X

@JustJakeSimpson @Khakionion Ohhhhhhhhhhhh

I don't understand the furore about the changes to Block. If my posts are set to public, then can't anyone I've blocked *already* view them, just by signing out / opening an incognito window?

@SoftLeafStudios @Snoopy_20111 What do you mean by "natively support?" There's some screen reader functionality built into both Unity (unity.com/blog/engine-pl…) and Unreal (dev.epicgames.com/documentation/…).

I’ll say this for the US Republican party: they don’t send me as much spam as the Democrats do.

Heathrow T2 surprisingly busy for 5am…

Man, getting from Heathrow to the nearby hotels is such a mess. Massive queue for taxis; bus that runs once an hour and will take 30mins to get to my hotel, which is about 1 mile away. I could walk it faster than that, except that you’re not allowed to walk through the tunnel…

@RouaniJihad @LizCouto Soon!

@LizCouto I'm guessing it's not out to the public yet?

Live at the #unite2024. We just unveiled our new Unity 6 sample scene - Time Ghost - and shared how Unity Sentis enabled the realist cloth deformations with AI 😎

@CiroContns @aras_p I’m coming to look at Sentis and NNs as being like a new kind of programming language - implementing functions through statistical inference, instead of through algorithms. For some problems that’s insane, but for other problems it’s very effective!

@aras_p Oh yes, that's what I meant. Previously Unity showed Sentis to generate dialogues for an NPC, something that can be exciting but also, of course, takes away from the artistry of writers and narrative designers. This one is a nicer application.

Watched the Unite keynote this morning. General vibe is positive. My favourite moment is Silvia and Richard on stage, to present the features used in Time Ghost. I mean, they showed an use case of AI and Sentis that actually sounds useful? 😆
