|
|
A node for driving body meshes from [XRBodyTracker] data.
|
|
</brief_description>
|
|
<description>
|
|
This node uses body tracking data from a [XRBodyTracker] to animate the skeleton of a body mesh.
|
|
This node positions itself at the [constant XRBodyTracker.JOINT_ROOT] position and scales itself to [member XRServer.world_scale]. Adding the body model as a child of this node will result in the model being positioned and scaled correctly for XR experiences.
|
|
The body tracking position-data is scaled by [member Skeleton3D.motion_scale] when applied to the skeleton, which can be used to adjust the tracked body to match the scale of the body model.
