GEMSTAR is the GEoMetry based Sensor simulation Toolchain for Automotive and Rail research.
The simulation tool supports the descision process for approval of operation domain (OD) and Operational Design Domain (ODD) for automated vehicles.
The simulation software GEMSTAR is a set of Unreal Engine 5.3 Plugins. Each plugin can be used standalone in Unreal to maximise flexibility. GEMSTAR combines exisiting simulation tools in a co-simulation and uses OSI standardized messages for logging and communication. It is designed to be tailored to your project specific needs by integration of SUMO, esmini and more by using the Game Feature Plugin system. Future updates will add new features: OSI Playback, OpenDrive map import, Traffic Lights, Radar, Interfaces to ROS2 and OSMP.

git clone https://github.com/DLR-TS/gemstar.git
cd gemstar
git submodule update --initRun PostGitPull_ReGenVSFiles.bat
Open GEMSTAR.sln
Build GEMSTAR
Run in "DebugGame Editor" configuration
A combined example map is located in the Content directory. It shows the integration of the different plugins. GEMSTAR is configured by using Config/DefaultGemstar.ini file. The OSI logs are saved in the Output directory.
To make a new map runnable with GEMSTAR only GEMSTARRoot is needed to load and set configurations for all activated GEMSTAR plugins. 3D assets can be added if needed.
Within each game feature plugin are maps that show the functionality of the respective feature. They are configured through Level Blueprints and configuration ini files.
