MVN Animate is a Motion Capture package by Movella.
The following steps show how to add the Godot MVN tracker to a project.
The addon files needs to be copied to the /addons/godot_mvn_tracker folder of the Godot project, and then enabled in Plugins under the Project Settings:
The plugin has numerous options to control behavior:
| Option | Description |
|---|---|
| Tracking - Position Mode | Controls the position of the character: - Free = Free Movement - Calibrate = Calibrate to origin on first frame - Locked = Lock to origin |
| Tracking - Body Tracker Name | Name for the XRBodyTracker |
| Network - Udp Listener Port | Port to listen for MVN network packets |
The character model must be in Godot Humanoid format. This can be achieved in the importer settings by retarteting the skeleton to the SkeletonProfileHumanoid bone map:
The body is positioned using an XRNode3D node configured to track the character body:
The body is posed using an XRBodyModifier3D skeleton modifier:
Note that the Body Tracker name should match the Body Tracker Name specified in the Plugin Settings.
MVN Animate must be configured for network streaming, which is an option only in the MVN Animate Plus and MVN Animate Pro licenses.
| Option | Description |
|---|---|
| Host | Host address (127.0.0.1 for localhost) |
| Port | UDP Port 9763 (default) |
| Protocol | UDP |
| Datagram Selection | Position + Orientation (Quaternion) |
