Animated escalator in Quill

 Well, I figured out why the loop glitched. Nothing to do with the loop, it was the alignment of the position of the first tread and then it's next position. Quill doesn't have an object snap function, so it was a case of zooming in very close and placing some markers. No noticeable glitch at the end. It's taken most of this week to get to grips with the animation timeline, controls, loops and sequences for this one section....however, it's striking when hearing Sally talk about the escalators and I believe this element adds to the feeling of descending into the abyss....
