XRBodyModifier3D ​

Experimental: This class may be changed or removed in future versions.

Inherits: SkeletonModifier3D < Node3D < Node < Object

A node for driving body meshes from XRBodyTracker data.

Description

This node uses body tracking data from an XRBodyTracker to pose the skeleton of a body mesh.

Positioning of the body is performed by creating an XRNode3D ancestor of the body mesh driven by the same XRBodyTracker.

The body tracking position-data is scaled by 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.
