Overview

When developing MR apps, ensuring compatibility with various room setups is critical. This process can be challenging and time-consuming. XR Simulator simplifies this process. It provides multiple built-in rooms for testing purposes, including three hero rooms and eight feature rooms, and includes convenient tools for creating custom test environments.
Visit the built-in rooms page for details, and explore the Synthetic Environment Builder to learn about constructing your own test rooms. If you prefer lightweight, JSON-based rooms, see JSON Format Rooms.
