Hey everyone, Today I have a rather simple question, I'll provide my current file as well as use screenshots to quickly get across what I mean by 'Vellum input geometry update per frame.'   Step 1: A disc: I've animated Arc End, creating a disc that closes itself, I have also grouped the inner edges.    2. Result A curtain if you will taking the shape of the disc.   What I would like: I require the disc to animate into the full circle and retain the vellum effect, essentially creating a circular curtain that closes itself. However Vellum only takes the input geometry from frame 1. I have played with rest blend, but did not get it work.   Here is my file:   vellum_circle.hiplc
