Are there guidelines on maximum NPCs possible in a mobile game?Is it possible to spawn NPCs and create random names and looks at runtime? 

Hi there , I'm trying to import a Unity asset bundle into Horizon Worlds and use ssetBundleInstanceReference.setAnimationParameterBool() to play animations on a model. However, I haven’t been able to find any tutorials or examples showing how to do this. Could someone please help or point me in the right direction? Here’s the official API documentation I’m referring to: https://developers.meta.com/horizon-worlds/reference/2.0.0/unity_asset_bundles_assetbundleinstancereference Thanks in advance! 

Is it possible to upload your own character mesh for a NPC? Or are NPCs limited to the canned assets and default character parameters? If the latter, is there some way to further customize the costumes? We'd like to do a medieval RPG game and need NPC's dressed in medieval attire, rather than the modern attire that is available by default.  

Is there some way to have more than 32 users in a single world for hosting large scale live performance events? 

Hi Meta team,Is there currently any support, or plans in the pipeline for cameras that can render to texture in Horizon Worlds?I’ve been brainstorming an idea for a digital arcade experience, but with the current toolset, it seems like building a remote control centre with might be a more viable direction.Being able to render a live camera feed to a texture (even at low resolution) would really open up a lot of creative possibilities for immersive experiences, arcade-style games, or surveillance-style puzzles.Would love to know if this is on the radar!Thanks

Hello, 👋Curious to know if the Gen AI tools are available for all users. I've updated my desktop editor (to Version 210.0.0.0.3.670), but I do not see the GenAI tools yet 😫. I'm located in California but have traveled often overseas. Would that have something to do with me not seeing the tools? I did submit a bug report just in case, but thought I'd ask if others are having the same issue.  A colleague of mine is in Arizona, and his editor got the tools just fine.Take care, everyone, and thanks for any insight! Can't wait to start working wihtthe GenAI tools

Can a user have a conversation with a NPC? Voice or text?

https://developers.meta.com/horizon-worlds/learn/documentation/typescript/api-references-and-examples/example-scripts-libraryThe other day I took way too long trying to get these 2 example snippets to work 1. Teleport a Player snippet, I couldn't get it to work. It just fails. I tried a lot of variations. Is there some secret spell I'm supposed to cast before running these snippets? 2. Attach an Entity to Player Snippet : I tried so many variations of this it's ridiculous, I could not get this code working. I deducted it's probably something with the properties of my entity, so I tried so many things, the only thing that was attached to my player was frustration.  These snippets really made me questions my abilities to problem solve. The most frustrating thing is seeing console logs after the code quietly fails with no explanation. I really want to learn this stuff. I feel like there's some obvious thing I'm missing that's so obvious it was left out of the

Title says it all--can I disable jumping, in both VR and mobile? I figure in mobile there's a way to remove the jump button?

Is there any way to unfocus a Custom UI using a script so the player does not have to do it themselves? I have a series of UI interactions and after they are over, I want to return the player to the main environment.

Hello Friends, I'm looking for a way to import glass models and textures. I've tried several variations of importing models/textures. From 1% opacity colours, alpha only pngs, etc. Models come in clean, textures always come in black. No other problems importing none glass models.I design most of my models in 3ds Max then export .fbx with turbosmooth options turned off.Any suggestions would be appreciated. If I missed a step, let me know.Thanks,

I want to make a player automatically grab an object when they bump into it instead of having to press the hold/grab button. Is there a way to do this? I don't see any method that would allow me to place an object in an avatar's hand.

Hey everyone,​I've been running into a recurring issue where Horizon Worlds crashes when I grab or re-grab objects that have physics enabled. It seems to happen more frequently with objects that have complex geometry or multiple colliders. The crash is especially likely if I throw the object and then grab it again before it comes to a complete stop.​I've submitted a formal bug report about this, but I wanted to check in here to see if anyone else has experienced something similar. Understanding if others are facing the same problem could help in identifying patterns or potential workarounds.​Has anyone else encountered this issue? Any insights or suggestions would be greatly appreciated!Thanks!

Hi everyone,I'm currently creating 3D assets for Horizon Worlds and using texture atlases to reduce draw calls. However, I’ve noticed that when I import multiple FBX files, even if they reference the same material/texture, it looks like Horizon Worlds duplicates the material for each asset.Would it be better to group those assets into a single FBX that shares one material across the mesh? Or is there a way to ensure separate assets can reference the same material instance without generating duplicates?Any insight on how Horizon handles this behind the scenes would be really appreciated!Thanks in advance.

Is there a guide for creating custom outfits?  

I am in the program and am very honored.thank you.

I'm trying to understand how to integrate gen ai with Horizon as a dev/creator... for example, suppose a user wants to generate a texture at runtime in-world, is there some way to connect with my external gen AI server?  If there is no way for horizon to allow for me to send to my external server, does horizon have in-world functions/methods that support the use of gen AI?  There was a session about this - but i had a prior commitment, will notes be provided - https://communityforums.atmeta.com/t5/Events-Calendar/Meta-Presents-Using-the-Power-of-Gen-AI-to-Master-Horizon-Worlds/ec-p/1312429#M48

Hi! I'm trying to learn how to upload a model with a metallic, shiny look. I've read the file naming guidelines, but unfortunately, after several attempts, I still can't get it to work. I must be doing something wrong. I'm exporting from Adobe Substance Painter.  Is someone willing to look at my files and explain what I'm doing wrong?

Hi All,I am posting in relation to these articles put out by the Horizon development team:https://developers.meta.com/horizon/blog/build-faster-smarter-genai-tools-meta-horizon-worlds-mesh-genhttps://developers.meta.com/horizon-worlds/learn/documentation/desktop-editor/generative-ai-creation-tools/generative-ai-mesh-generation-toolI spent some time over the last couple days trying these out and they are a lot of fun to use; but I have a couple questions:1. Is it possible to get a list of the prompts and models generated used in the demo video? I would like to know if there are any special keywords that give certain kinds of results. I am guessing some terms are more effective than others.2. Is it possible to use images (instead of or in conjunction with text) to create meshes? About a month ago, Andrew Price (Blender Guru) did a breakdown of several image-2-mesh tools including Trellis, Prism, Rodin, Hunyuan and Backflip. Being able to use 2d artwork to drive the mesh creation tool cou

Hello,I’ve been doing some tests and understand that audio files can't be uploaded, so I started experimenting with the sound recorder. However, I’ve run into a snag trying to figure out where the mic signal is being sourced from by default.I'm using a Focusrite 1820 in my studio setup, but I haven’t had any luck getting any recordings. Is there a video or guide that walks through the setup process? Or is there a specific setting that lets you select the recording device?Here’s the documentation I’ve been looking at:https://developers.meta.com/horizon-worlds/learn/documentation/code-blocks-and-gizmos/use-the-sound-recorder-gizmoAlso would being able to upload sound files be in the development pipeline in the future?

Hi,I have two local scriptsSomeLocalItem.tsAnotherLocalItem.tsSomeLocalItem has reference to Entity with AnotherLocalItem.I want:1) Inside SomeLocalItem invoke method on referenced AnotherLocalItem.2) Inside SomeLocalItem read some property from AnotherLocalItem.Note, both scripts are local, so Behaviour.ts doesn't work here without rewriting it to work locally. Is there simpler way?SomeLocalItem.tsimport * as hz from 'horizon/core';import { AnotherLocalItem } from 'AnotherLocalItem';class SomeLocalItem extends hz.Component<typeof SomeLocalItem> {  static propsDefinition = {    anotherLocalItemEntity: { type: hz.PropTypes.Entity }  };  start() {    this.connectCodeBlockEvent(this.entity, hz.CodeBlockEvents.OnButton1Down, () => {this.onButton1Down();});  }  onButton1Down() {    this.anotherLocalItem = this.props.anotherLocalItemEntity as AnotherLocalItem; // This doesn't work, how to assign the entity to the component?

I've created a world where I'm the collaborator. The world has the following publish settings: Visible to Public = OffMembers-Only World = OffBeta World = On / Off (it doesn't matter)Available Through = Mobile and web onlyThe issue is clicking on the world link (URL) on my Android phone opens up a blank page on the Meta Horizon app (see attached). I'm not able to access the world. This is only an issue for a non-collaborator (i.e. not invited user) is logged into the Meta Horizon app. I don't think it's a permissions issue because: A) The above publish settings should make the world accessible to non-collaborators and B) I can enter the world just fine on the web as a non-collaborator (i.e. not invited user). Since there's a competition going on and Feedback Festival is happening right now, this bug should be communicated to Meta SMEs so that they know they should access worlds via their desktop. This bug also of course needs to be fixed!This is what I see after clicking on the world '
