Unreal Engine Scenario Simulation
R2026bSimulate UAVs in pregenerated and customized 3D scenes, and generate simulated high-fidelity sensor readings (requires Simulink® 3D Animation™) using the Unreal Engine® from Epic Games®. This environment is available in Simulink and runs on Windows® and Linux® only. To learn more, see Unreal Engine Simulation for Unmanned Aerial Vehicles.
As an alternative, UAV Toolbox also provides a cuboid environment that enables you to rapidly author scenarios and generate low-fidelity sensor data. For more information, visit Cuboid Scenario Simulation.
