Meta Horizon v214 Release Notes
This week in v214 we are introducing the World capacity guidelines dialog, giving creators more insight into their world capacity information. Additionally, we opened up the avatar pose gizmo API to all creators, which includes two new events: OnPlayerEnterAvatarPoseGizmo and OnPlayerExitAvatarPoseGizmo, which will trigger when a player enters or exits a seat. We also have quality of life fixes including increasing entity limits under a single parent object, giving creators significantly greater flexibility to create complex hierarchies. Finally, we have a large volume of community requested bug fixes including Mesh GenAI softlocks.
Please note that from v215 onwards, we are changing the scripting directory structure to not include the World name in the folder name. This is done to prevent malicious attacks via bad actors. In case you are using a source-control system for managing scripts, you will need to reconfigure the setup after the update.
Read on for more details on Meta Horizon v214:
New Features
- Introducing the World capacity guidelines dialog: Desktop users now will be able to see their world capacity information for Objects, Simulation and animation, World vertex count, and Sounds, bringing the desktop editor more in-line with the functionality already available in the VR Editor. Find this option in the Main Menu within the desktop editor and select World Capacity .
- The avatar pose gizmo typescript API is now open to all creators. This includes two new events: OnPlayerEnterAvatarPoseGizmo and OnPlayerExitAvatarPoseGizmo, which will trigger when a player enters or exits a seat. These new events will provide more flexibility and control for creators building interactive experiences. Learn more here.
Quality of Life Improvements
- Increased the entity limit from 1000 to 3000 under a single parent, which gives creators significantly greater flexibility to create complex hierarchies.
- Added UI to all Mesh GenAI features highlighting the 500 character limit max per prompt, making it more clear to creators that there is a character limit up front rather than waiting for a response with an error.
- Improved object manipulation in editor mode.
- Desktop world editor now supports deeplinking. Note: only the desktop editor, installed from the standalone installer will have deeplink capability.
- Horizon Desktop Editor GenAI tools are now available in Australia and New Zealand. This includes: Typerscript, sound effects, ambient audio, skybox, and mesh and texture generation tools.
- Typescript generation is now powered with Llama 4, Meta's newest LLM, enhancing its quality and accuracy.
- Improved object manipulation in editor mode.
Bug Fixes
- Fixed a bug where generating a thumbnail for meshes that have a transform would result in artifacts.
- Fixed a bug where uploading multiple meshes at once would result in a pink texture artifact.
- Fixed a bug where generating a thumbnail for a legacy group node mesh would fail to capture the entire mesh.
- Fixed a bug where the release notes would not be fully scrollable when viewing within the desktop editor.
- Fixed a bug where the Mesh GenAI panel could be softlocked when submitting prompts after the server returns an error.
- Fixed a bug where the world rating would not update after adding the rating.
- Fixed a bug where GenAI audio assets could be stuck in a continuous loading state after being dropped into a world.
- Fixed a bug where minimizing the bottom panel would trigger a visual defect within the editor.
- Fixed a bug where the camera position was not saved after entering and exiting preview mode.
