Detailed Description

Instantiate a mesh along the TrackFlowSpline. This is for discrete mesh pieces. If you want a pipe or road those are built into the Mesh settings within TrackFlowSpline.

"Forward" is assumed to be the Z direction; we align prefab Z with spline tangent (blue), and prefab Y with spline binormal (green).
