Production tutorial / tooling walkthrough (real-time mocap streaming)

Contributions

• Walks through enabling Live Link 2.0 in Unreal Engine 5 and installing the MoBu Live Link plugin by placing the correct binaries in the MotionBuilder 2022 plugins folder
• Shows connecting via the UE Live Link device and a Message Bus Source, streaming the mannequin skeleton with the subject selector, and enabling camera sync
• Drives an in-scene character through an animation blueprint with a Live Link Pose node fed a local-space ref pose, and warns that cloth and dynamics can crash when an actor leaves the capture volume, recommending the Chaos implementation

Context

Practical previsualization/virtual-production workflow connecting MotionBuilder 2022 to Unreal Engine 5 via the Live Link plugin, rather than building on a research lineage.

Correctness

Studio/tooling practice, not peer-reviewed; steps are version-specific to MotionBuilder 2022 and UE5 and reflect hands-on experience, including the noted cloth/dynamics crash on volume exit, so exact menus and stability may differ across versions.

Clarity

Step-by-step and accessible; following it once end-to-end is the way to absorb it, no second analytic pass needed.

How to read it

Follow along in the actual software with matching versions; pay attention to the binary-placement step, the Message Bus connection, the local-space ref pose, and the Chaos-cloth stability warning.
