A trail whose width follows each particle's own local X axis, independent of the path and of the camera. The axis comes from the particle's full orientation - its rotation, combined with the emitter's and the system's orientation - so the ribbon can lie flat, stand upright or twist with its particles.

With no rotation authored, every point's width runs along the emitter's local X axis. The direction of the path does not enter the width at all, so a ribbon whose path turns toward its own X axis narrows at that point, and one seen edge-on disappears.
