LG Mothballed Its Unity AV Simulator in 2022
An HDRP Unity simulator for autonomous vehicles that shipped with Apollo and Autoware integration, then LG suspended all development in 2022.

What it does
SVL Simulator is a Unity HDRP-based multi-robot simulator for autonomous vehicle developers. It offers out-of-the-box integrations with Baidu Apollo and Autoware.auto, generates HD maps, and targets teams who want to test autonomous vehicle algorithms without custom integration work. The project runs as a standalone executable on Windows and Linux, though the README concedes Windows currently delivers better performance.
The interesting bit
The project is now a frozen artifact. LG halted all development, bugfixes, and pull-request reviews on January 1, 2022. The final 2021.3 release is tethered to LG’s WISE cloud service for asset downloads and simulation orchestration; the README says stripping out that dependency would require a fork and a manual Unity build, and LG has no plans to open-source the WISE backend.
Key highlights
- Repo description labels it a
ROS/ROS2multi-robot simulator for autonomous vehicles - Pre-integrated with Apollo and Autoware.auto platforms
- Generates HD maps for full-system validation
- Licensed to permit non-commercial derivative works and community forks
- Over 500 public forks already exist
Caveats
- The 2021.3 release depends on the
WISEcloud service, which LG only committed to maintaining through June 30, 2022; the WISE source will not be released - LG explicitly states there are no plans for new releases, bugfixes, or merging community contributions
- Requires a high-end desktop: LG recommends a 4 GHz quad-core CPU and an Nvidia GTX 1080 with 8 GB of VRAM
Verdict
Worth a look for researchers or hobbyists who want a frozen but functional Unity AV simulator to fork for non-commercial experiments. If you need active maintenance, living documentation, or a cloud-independent binary, this is explicitly not it.
