A travelling node is the ghost of the track content or part of the track content. The default travelling node is different depending on the type of track content. For example, a character’s default travelling node is its hips, but a cube’s default travelling node is the entire cube.

A travelling node displays as a gray triangle in the Viewer window and follows the track contents along the clip trajectories.

By default, the travelling node displays on the floor (XZ plane), underneath the part of the track content that defines the travelling node.
