Releasing the alpha of Unreal Robotics Lab — an open-source Unreal Engine plugin with full MuJoCo physics. Photorealistic rendering and accurate contact physics. No compromises on either side. GitHub: github.com/URLab-Sim/Unre… Paper: arxiv.org/abs/2504.14135

@yoav_chn Definitely! It's designed to be asset-agnostic, so you can import any MJCF or XML model directly.

@JonEmbleyRiches Does this work with a unitree go2?

@Shi_Soul Not directly; MJWarp/MJLab are best for parallel RL. URLab embeds MuJoCo for high-fidelity data gen & vision eval. An interesting direction is leveraging UE PCG in URLab to generate DR scenes for MJLab to load for training, then zero-shot eval in URLab. Open to exploring!

@JonEmbleyRiches Cool! just wondering, is there any plan to support parallel simulation & RL training?

@JulienBlanchon Thanks! Technically yes, though currently untested. You would package the project for Linux, which is already working, and run via NVIDIA Container Toolkit with the -RenderOffscreen flag. I can create a Dockerfile if there's enough interest.

@JonEmbleyRiches Amazing ! Can it run in an headless way inside a docker ?

Alpha release — open source under Apache 2.0. If you are working in robotics simulation, I would love to hear from you. Check the roadmap on GitHub for upcoming features and feel free to open an issue or PR.

Features: - Import or author robots natively - Deploy policies live in-engine - Possess robots with real-time input - Turn any mesh into a physics object - Record, replay, and adjust sim speed - Stream over ZMQ or ROS 2 - Scale to dozens of robots
