Meta Horizon Worlds V171 is here! This week we’re kicking off Summer Carnival 🌞🎪 and rolling out a few quality of life improvements, including updates to sound settings that will give you more control over who you can hear (and vice versa) and search and discovery improvements for worlds and events. We are also starting to roll out an update to help world creators use and optimize scripts when building, along with a number of bug fixes. Read on for more!

Quality of Life Improvements
Voice Channel
We’re improving our sound settings to give you more control over who you can hear (and who can hear you) while in Worlds. The previous Voices and Voice Mode settings are being replaced with a single setting called Voice Channel that makes it easy to choose who you want to interact with.
There are two Voice Channel options:
- People you know: With this setting, you’ll only hear and be heard by people you know, a.k.a. people who follow you and who you follow back within Meta Horizon. Other people’s voices will be filtered and sound like quiet and friendly background noise. (In the past, we’ve referred to these “filtered” voices as “garbled.”)
- Everyone: With this setting, you’re open to hearing and being heard by everyone in the world. However, if someone has their voice channel set to only hear people they know, their voice will sound filtered to you.
To adjust Voice Channel settings, go to Settings > Sound and select your desired Voice Channel option.
Improved Search + Discovery
A
previous experiment to improve the search experience has now rolled out to everyone! As a reminder, we were testing out a new “All” default tab that would return both worlds and events when searching.
Separately, we are now testing out a new feature in which worlds will begin showing up in a new Worlds tab within the Horizon Store. We believe this will help users discover more experiences that they want to engage with.
Web and Mobile- We made the sprint field-of-view transition more responsive and reduced the acceleration of the effect on web and mobile.
- The People profile in the Horizon menu now shows a back button on web and mobile.
- We have added a new shelf of “Hangout Worlds” to the Horizon Feed on mobile.
Creators- We are beginning to roll out an update that will make file-backed scripts the default for all new worlds. This changes how Meta Horizon Worlds stores scripts—but more importantly, it enables you to use more scripts per world, unlocks larger scripts and improves travel times. It should also make script editing more reliable.
Check out the Help Center for more information on this update, including the benefits of file-backed scripts, how to opt in or out, and more.
Note: There is currently no plan to automatically update existing worlds to file-backed scripts.
Highlighted Bug Fixes
Here are some highlighted bug fixes for this week’s release.
General- We fixed a bug where the sound effect would not play when claiming a reward in the Horizon menu.
- We fixed an issue where door information failed to load in worlds containing large numbers of doors.
- We fixed music not playing when traveling between worlds on web and mobile.
- We fixed the World Volume slider in the Settings menu, which was not functioning in certain worlds in VR.
Creators- We fixed a rare issue that could cause script properties on spawned assets to be wired to the wrong objects.
- For worlds using file-backed scripts, line numbers will now be correct in the scripting console and logs as soon as the world is loaded in Edit mode. This will only be true for scripts that are modified after this change.
