Publishing error: You are attempting to publish a world with pre-release features.
Hi, I have a World and I want to participate in the Creator Competition: Elevate Your Mobile World. When I try to use new features—such as importing an FBX file or inserting assets with the new format—there is no problem in previewing the World. However, since my World was originally created in 2022, I receive the following error message when attempting to publish: "You are attempting to publish a world with pre-release features." It seems that new features are recognized as pre-release features in worlds with older original metadata or internal structure. Even if I delete all entities and scripts in the World except for the imported FBX or inserted asset, I still receive the same error when I try to publish it. On the other hand, if I create a brand-new World and import the same FBX file or insert the same asset, publishing works fine. Additionally, in my older World, I can't assign custom textures to shapes, and the Build > Shapes menu lacks newer items like Cube Beveled or 10 x 10 Plane. Since the competition requires updating a previously published World, what would you suggest? Can I recreate and update my World from scratch to avoid the publishing error? If I do that, the new World would not meet the requirement of being originally published before June 30, 2025. Any guidance would be greatly appreciated. Thank you in advance!Collab request for upcoming creator competition
Hey! I’m looking to team up with a strong Horizon Worlds coder in the community. I’m a game designer with ~10 years in games (VR focused), ex-Meta (3+ years, QA Lead, including time on the desktop editor), and the past 12 months full-time building in Horizon as a creator. I got MHCP partner status back in Dec 2025. What I bring: Game design (micro, mid and macro loop theory tested and implemented) Discovery + growth (300,000+ impressions on a single world) Thumbnail + iteration systems (I know how to get clicks and test properly) Game concepts, lore, and player experience Playtesting, feedback loops, and weekly event systems Art direction Overall production Where I’m weaker: My code quality is mid, I can get things working, but not clean, scalable, or robust. Who I’m looking for: Strong Horizon Worlds coder / engineer Can build clean, reliable, non-buggy systems Fast at prototyping Serious about competing Experimental mindset. Open to fast iterations to ‘see what works’. Wants a long-term collab, not a one-off (If trial project goes well) Goal: Pair up as a designer + engineer duo to win an upcoming Meta Horizon competition. Intention is to do a mini trial project first to test fit. If you’re strong technically but know your design / discovery isn’t there, then we’ll complement each other well. My latest work for an idea of my style: https://horizon.meta.com/world/10241323577005469 Was also featured in last months Mentor playtest here: https://www.youtube.com/watch?v=oxU-vI1ug2U If interested, comment here and we can move to DMs. Cheers!Week 49 as a full-time Horizon Worlds Creator
Hey fellow creators, thought this might be interesting to read... Honestly I was overwhelmed by the multi script feature set required to make a system like this work, but this week I finally pulled the trigger. This week I implemented collectible pet companions. What I actually Implemented: Pet duck system where the ducks can be equipped and sit on your shoulder Perk system where ducks have unique player ability enhancements Pet Duck Store UI and Duck Locker UI so you can choose what pet you want to take into the next round. Currency system, where progress in the game rewards you with exponentially greater cash out to spend on more powerful pet ducks. What I learnt: At this later stage in development, adding major features that touch other systems means a wider code base architecture review is needed each time. I found that decisions I made prior, before considering this latest feature, may need to be changed to allow the new feature. The importance of PRD docs as part of the AI assisted coding workflow. Introducing a system of task management in my cursor project allowed much easier onboarding of fresh agents as I continue to wrestle with context window management. Next weeks goals (Well, by this Fri): Some Polish / delayed scope of the pet duck system Daily Login Rewards Game Link: https://horizon.meta.com/world/10241323577005469 Anyone still reading, have you built any similar 'collectible pet' systems yourself?Congratulations to the winners of the Meta Horizon Creator Competition focused on "Mobile Innovation”

Finally finished this project with this original combat mechanic designed as a mobile only game! It's a fantasy adventure turn-based RPG where you spell words to attack the enemy. Clear each floor to earn XP, more health, and of course LOOT! The game starts out easy while you familiarize yourself with the mechanic. Then you start earning armor and weapons to take on higher floors. Use potions to recover HP, and scrolls to summon up to 2 extra letters at a time. This progression system was by design made to be addictive and challenging tracking 4,700+ data points and a custom word engine using JSON files for precise adjustments to difficulty for the 3 player archetypes: casual gamer, the dedicated gamer who put in their time, and those gamers who choose to pay-to-win. Custom leaderboards use World Persistent Variables which allowed me not to track just scores, but also what words earned them their ranking (after filtering out 500 words to stay appropriate to general audiences). Please try it out and vote for the project on DevpostAdventure Engine submission
My contest submission: https://devpost.com/software/adventure-engine Thanks to the huge number of people who helped me out with NoesisGUI! Once the NoesisGUI implementation becomes more stable I look forward to reworking the Adventure Engine UI in a simpler way but I'm very happy that it basically works the way I had imagined despite all the work arounds.NoesisGUI world
For the next contest I've used NoesisGUI, Meta AI images and a simple JSON file to create a mobile-friendly retro text adventure engine. People can create text adventures in JSON and Meta AI images with no coding knowledge. Demo link: https://horizon.meta.com/world/827765603325078 The demo saves progress in PPV variables so people can come back but it really should not take long to play. If there is interest I can put up a document next week describing the JSON file format and create worlds for people that want to run their own games using the engine. I'm thinking that it might be fun to create VR worlds with arcade game rooms that have retro games like these.
