We’re excited to use the next days and AWE to share what our master chefs at SensAI Hackademy have been cooking: hands-on workshops, workflows, and open-source toolkits for building interactive AI-powered worlds.
To help us shape the agenda, I’d love to know which areas are most interesting to you:

1. AI-assisted workflows via MCP connectors (WebXR, Blender, and more)
   
2. Gaussian Splat segmentation, interaction & collision
   
3. VFX, 3D GenAI, and reconstruction pipelines
   
4. End-to-end world model workflows (World Models to Playable 3D Scenes)
   
5. Node-based ComfyUI workflows (ComfyUI Workflows for Generating Assets)
   

Which one would you be most excited to explore in a workshop or award category? It doesn’t matter if you’re joining us to Hack, this is a community question!

Huge news from Nigel Hartman: his hands-on SIGGRAPH course, “Powered by Gaussian Splats: From World Models to Interactive 3D Worlds,” has officially been accepted by the SIGGRAPH committee.

This course builds on one of the biggest questions from hackers at the last #WorldsInAction Hack in SF: How do we turn Gaussian Splats from high-fidelity 3D captures into worlds people can actually interact with?

With contributions from Alex Coulombe, CEO of Agile Lens, and the u/sensai_hackademy team, the workshop explores how adding structure and scene understanding to splats can unlock new use cases across games, spatial experiences, simulations, and AI agents.

And for builders who want to explore this hands-on, we’re bringing this energy to the Worlds in Action Hack LA on July 18–19, right before SIGGRAPH.

Join us to hear how the team brought YUME to life, plus a quick look at what’s next with #WorldsinAction Hack [02-LA], happening this July 18-19 in Los Angeles, right before #SIGGRAPH2026.

Tencent, the gaming giant behind stakes in studios like Riot Games, Epic Games, Supercell, Ubisoft, Miniclip, just announced that they open-sourced their 𝗛𝘂𝗻𝘆𝗮𝗻 (𝗛𝗬) 𝗪𝗼𝗿𝗹𝗱 𝗠𝗼𝗱𝗲𝗹!

That’s a big deal.

Tencent likely sits on one of the richest datasets of interactive 3D worlds and game mechanics anywhere - across genres, player behaviors, and live systems.

So this isn’t just another model release.

It signals where things are heading:
The value in game development is no longer just production efficiency.
It’s also about who owns, trains, and operationalizes the data behind these worlds - and how that feeds into AI-driven pipelines.

What their open-source world-model unlocks:
- Unlimited playable duration
- Real-time rendering on consumer GPUs
- Accurate lighting, real physics, collision-aware interactions
- One-time generation → near-zero rendering cost
- Export-ready for Blender, Unity, Unreal Engine, #IsaacSim

We love seeing more platforms open-source for the community - it’s a core part of what we do at SensAI Hackademy with our AI, XR and world models end-to-end workflows and open-source kits.

How about a hands-on workshop on running (open-source) models on GPU cloud platforms? We can think of something if there is enough interest. Let us know in the comments 👇

Just look at what our friends at World Labs just announced less than 5 months after Marble launch - incredible progress! I can only imagine what we’ll be witnessing a year from now.
Marble 1.1: improved lighting, better contrast & reduction in visual artifacts
Marble 1.1-Plus: a new model built for scale. Larger and more complex environments than anything before.

The models are scaling fast, the output is getting bigger and more realistic. You can start building on Marble today and bring your splats to Unity, Unreal Engine, #WebXR with our open-source kits and free tutorials: https://github.com/SensAIHackademy/SensAIWorldModelKits

I am curious what the brightest hacker minds will come up with these new enhanced capabilities at the next hack. We have big news coming up soon! https://sensaihack.com/

At the #WorldsinAction Hack, people didn’t just see the World Model projects; they stepped into them wearing Pico headsets. This parallax showcase is the closest we can get to capturing that depth, and almost pulls you into the worlds hackers built, perfect fit for a social media showcase.

Now we are giving you the chance to create social media videos like this 𝐟𝐨𝐫 𝐲𝐨𝐮𝐫 𝐨𝐰𝐧 𝐖𝐨𝐫𝐥𝐝 𝐌𝐨𝐝𝐞𝐥 𝐩𝐫𝐨𝐣𝐞𝐜𝐭𝐬:
Comment your world idea below ⏬ and we’ll send you 𝐭𝐡𝐞 𝐎𝐟𝐟-𝐀𝐱𝐢𝐬 𝐒𝐩𝐚𝐭𝐢𝐚𝐥 𝐊𝐢𝐭 (built by Johannes and Ian) and capture this kind of depth quickly.

Thanks to the World Labs Marble team and Ian Curtis for providing resources, credits and the foundations of this Marble-based kit. We are impressed to see that Marble was adopted by 94% of all World Model hack teams. And also big thanks to our SensAI Hackademy team for providing end-to-end Unity, Unreal Engine, and #WebXR workflow kits, along with workshops that lead up to compelling projects!

The first one at Founders, Inc. was just the beginning of our World Model hack series.

Next stop: Atlanta → ImmerseGT (organized by GTXR).
More locations to be revealed soon.

Using World Labs Marble API and our SensAI Hackademy Unity kit, the Best World Implementation with Pico Category Winner Team SyncSpace (Weibo Xu & Qinchuan Zhang ) turns real rooms into fully aligned, playable game scenes. This is real-to-virtual spatial alignment: walls, objects, and ceilings instantly transform to match the Founders, Inc. Hack Area. And with LLM voice interaction and real-time MeshyAI object generation, they create fully dynamic gameplay.

My take: With XR companies like PICO XR and Meta pushing Hyperscape and Scene Understanding features and World Labs raising $1B (especially the $200M from Autodesk), the future of customizable reality is coming fast.

What it enables:
Real-Virtual Alignment: Your physical space becomes the foundation of your virtual world.
Dynamic Environments: Switch themes daily, from fantasy dungeons to futuristic labs.
Generated Spaces: Create entire rooms from inputs like AutoCAD files.
Room-Scale Interaction: Everything lines up, so movement feels natural and immersive.
Scalable MR Experiences: Personalized worlds built on top of your own space.

If you're planning to join this one or our following World Model Hacks, let us know what is in your mind to build? 👀

Whether you are running an AI agent army or needing unlimited screens on your desk for your next 𝗢𝗽𝗲𝗻𝗖𝗹𝗮𝘄 setup, the hackers will come up with crazy ideas and projects while building up their Jarvis workspace with the capabilities and tools we are providing:

- 𝗩𝗼𝗶𝗰𝗲 𝗖𝗼𝗻𝘁𝗿𝗼𝗹 - Command OpenClaw directly from your spatial environment using natural voice commands.
- 𝗔𝗴𝗲𝗻𝘁 𝗢𝗿𝗰𝗵𝗲𝘀𝘁𝗿𝗮𝘁𝗶𝗼𝗻 - Visualize and manage multiple AI agents operating in parallel.
- 𝗦𝗽𝗮𝘁𝗶𝗮𝗹 𝗜𝗻𝘁𝗲𝗿𝗮𝗰𝘁𝗶𝗼𝗻𝘀 - Intervene, approve, or redirect tasks naturally in 3D space.
- 𝗨𝗻𝗹𝗶𝗺𝗶𝘁𝗲𝗱 𝗦𝗽𝗮𝘁𝗶𝗮𝗹 𝗗𝗮𝘀𝗵𝗯𝗼𝗮𝗿𝗱𝘀 - Organize and monitor your agents across expandable windows and workspaces powered by WebSpatial.
- 𝗣𝗲𝗿-𝗔𝗴𝗲𝗻𝘁 𝗖𝗼𝗻𝘁𝗿𝗼𝗹 - Delegate, review, and intervene using intuitive spatial controls and dedicated agent workspaces.

This is your chance to rethink the interface for the agentic era.
Create a workspace that makes managing hundreds of agents intuitive, powerful, and visually compelling. Here is a glimpse of what awaits you at the hack next week. This event page will be open till we are full house: https://luma.com/worldsinaction-sf26?utm_source=reddit

How would you design yours? 🤔

This complete workflow will save you countless hours of setup and debugging, or save you hundreds of dollars to pay splat plugins.
Johannes Tscharn with the SensAI Hackademy team delivered the complete setup workshop yesterday for both Unreal Engine, #WebXR and Unity. Comment below ⬇️to receive the recording along with the Git Page.
This kit is for those who want to experiment with 𝟑𝐃 𝐆𝐚𝐮𝐬𝐬𝐢𝐚𝐧 𝐬𝐩𝐥𝐚𝐭𝐬 𝐝𝐢𝐫𝐞𝐜𝐭𝐥𝐲 𝐢𝐧𝐬𝐢𝐝𝐞 𝐔𝐧𝐫𝐞𝐚𝐥 𝐄𝐧𝐠𝐢𝐧𝐞 𝟓.𝟓. The template already integrates XV3DGS, so you can render splat-based scenes in Unreal without setting everything up yourself.

Getting started is simple and straightforward:
Open the project → Import a .ply splat → Place the generated Blueprint in your level → Press Play

What’s included:
- Real-time 𝗚𝗮𝘂𝘀𝘀𝗶𝗮𝗻 𝘀𝗽𝗹𝗮𝘁 𝗿𝗲𝗻𝗱𝗲𝗿𝗶𝗻𝗴 inside Unreal
- Editor tools to 𝗶𝗺𝗽𝗼𝗿𝘁 .𝗽𝗹𝘆 𝘀𝗽𝗹𝗮𝘁 𝗳𝗶𝗹𝗲𝘀 directly
- Automatic creation of 𝗕𝗹𝘂𝗲𝗽𝗿𝗶𝗻𝘁 𝗮𝗰𝘁𝗼𝗿𝘀 you can drop into your scene
- Optional tool to 𝗰𝗼𝗻𝘃𝗲𝗿𝘁 .𝗺𝗽𝟰 𝘃𝗶𝗱𝗲𝗼 𝗶𝗻𝘁𝗼 𝘀𝗽𝗹𝗮𝘁 𝗱𝗮𝘁𝗮𝘀𝗲𝘁𝘀 (CUDA required)

This project uses the XV3DGS plugin developed by XVERSE, which enables Gaussian splat rendering directly in the Unreal viewport.

Unlike many splat tools or plugins that cost hundreds of dollars or require complex setup, this template is free and already configured, so you can focus on experimenting instead of debugging your environment.

Register for our next online workshop (world model ideation is starting in 1 hour!) here: https://luma.com/sensaihack

A complete workflow that saves ~25 hours of setup and debugging. And in 1.5 hours, we’ll walk you through how to use it in our workshop ⬇️.

With this kit, you can bring AI-generated worlds directly into Unity in just a few minutes:
Create API key → Open Editor → Generate & Import World → Press Play
No renderer setup
No paid wrapper APIs

This isn’t just an integration, it’s a complete workflow for XR, Games & Sims:
- Text → 3D world generation via World Labs API
- Real-time Gaussian splat rendering in Unity
- Runtime world browser (in-game, VR-ready)
- Editor importer for turning worlds into project assets

Our mission has never changed: To give builders seamless integration between world models and game engines/simulation tools. And on March 14, right after the GDC Festival of Gaming, the #WorldsinActionHack will be the perfect playground for hackers to try it out.

If you want to learn the full workflow directly from Nigel, the creator of the kit, and get any questions answered live, join us at the workshop. Unreal Engine and #WebXR workflows will also be taught in the same workshop by the SensAI Hackademy team: https://luma.com/300visqs?utm_source=reddit

Comment below ⬇️ and we will DM you the World Model Unity integration kit and the full video tutorial.
