Asset Library

Updated: Dec 12, 2025
New in Meta XR Core SDK v83
The Asset Library is available in Meta XR Core SDK v83 and later.
The Asset Library is a collection of 3D models generated by AI that you can use to rapidly prototype and produce your scenes in Unity Editor. All assets are free to use and provide four levels of detail (LOD) to help you optimize your scene for performance or detail.
This guide provides instructions on how to search for assets and add them to your project.

Prerequisites

Before proceeding with this tutorial, complete the setup steps outlined in Set up Unity for VR development to create a project with the necessary dependencies.
Confirm that Meta XR Core SDK v83 or later is installed in your project.

Using the Asset Library

Step 1: Access the library

To open the library’s search interface, select Meta XR Tools > Asset Library from the menu at the top of your editor.

Step 4: Select an asset and add it to your scene

  1. Select the Level of Detail (LOD) setting that best meets your visual fidelity and performance balance requirements.
    For example, LOD 0 is the most detailed and has the highest polycount, which increases CPU and memory usage. LOD 3 is the least detailed and uses the least CPU and memory.
