The Desktop Editor, launched in February, enables importing assets, building 3D landscapes, and implementing game logic with TypeScript, making worlds playable and multiplayer-capable.

Meta is rolling out new AI-powered NPCs in Horizon Worlds that can engage in real-time conversations, provide guidance, and react dynamically, significantly boosting interactivity on the platform.

Earlier this month, Meta introduced generative AI features for Horizon Worlds' desktop editor, making it easier for users to create environments with less technical skill required.

This initiative is part of Meta's broader strategy to increase engagement and differentiate Horizon Worlds from competitors like Rec Room, Roblox, and VRChat, which currently feature scripted NPCs.

Meta's island generator allows users to specify island dimensions and features, with AI adding elements like trees, grass, and buildings based on text prompts, all of which remain editable.

These NPCs will respond dynamically to player interactions, blending scripted dialogue with AI-generated responses and using a library of different AI voices.

While Meta has experimented with NPCs before, this new update offers full customization and more realistic conversational abilities, marking a significant step forward.

In select regions including the US, UK, Canada, EU, Australia, and New Zealand, creators can generate 3D meshes, textures, skyboxes, and sound effects using AI within the editor.

Upcoming features include character customization with traits like backstory and voice, and AI NPCs triggering in-world actions later this year to enhance immersion.

Meta initially teased the Environment Generation feature as a broad 3D world generator, but it has now launched in a limited form focusing on island creation with customizable size, shape, and style.

This update, available via the Worlds Desktop Editor, allows developers to design embodied characters with unique appearances, backstories, and response instructions for the first time.

Developers will soon be able to create customizable NPCs capable of lifelike voice conversations, with attributes like names, personalities, and dialogue styles.
