Question

The Elephant in the Room?

On Friday, many of our worlds were abruptly affected by an issue where triangle warning icons and exclamation markers began appearing throughout our environments. From what creators are reporting, this appears to primarily impact worlds built using Trimesh assets, while older worlds built mostly with primitive shapes seem unaffected.

This issue is occurring globally across both Mobile and VR users, making many worlds difficult or impossible to properly test, showcase, or publish.

Has Meta provided any official update regarding:

  • The root cause of the Trimesh issue?
  • Whether a fix is currently being worked on?
  • An estimated timeline for resolution?
  • Whether the June 15 publishing deadline will be extended for creators impacted by this platform-wide problem?

Many creators have significant projects that are effectively on hold due to this issue. With the publishing deadline approaching, clarification from the Horizon team would be greatly appreciated.

Thank you

Hello!

If you are able to, please submit a ticket to the Developer Support Portal and provide as much info as possible for this issue.

Thank you!

All my worlds are like this also.  Thanks for the post because I was surprised there were no other comments on here, but there was discussion on Reddit regarding this.  I was going to look at updating the desktop editor and reloading my world in it because I have not for a while, but it sounds like that is not a fix.

I can see in what was my moat popular world, that only the few pre-made meta assets that I had used are loading today.  A few days ago I tried to join it in VR and I could see the bots walking on assets that did not load, and only the meta AI generated or bots or meta pre made assets loaded then - nothing custom was there.

Something similar happened to just my world once in an unpublished state and it fixed itself after a few days, so I am hoping that is the case here...

Anyways I did not try to join any non-recommended worlds in the app, but if this affecting small time creators then I wouldn't be surprised the percentage of unplayable worlds is beyond significant.

As of this morning it has been restored.  Its the 15th lol!!!  So many of us tossed around the idea that maybe just maybe the server glitched out.  So many have been going over to VR Chat to continue their building journeys.  I have only been creating for about 6 months so I believe I came in at the right time to learn something new and soak it all up.
