Hey everyone. I am trying to make a sequence in which I have some 3D text that comes together from a bunch of shattered pieces. Right now I just have a simple voronoi fracture setup and some force applied to make it shatter. I was originally just going to render the sequence then play it in reverse in After Effects when compositing, but I realized that if I want to apply motion blur and have it blur in the right direction, I will have to sim it in reverse. Is there a way that I can do this so that it starts broken up and then comes together?

assuming your geo has constant topology,
you can just reverse post sim using by appending TimeBlend/TimeWarp or TimeBlend/Timeshift and reversing the time

if you need you can recompute v using Trail SOP, but this is not necessary unless you are using v in any way, for mblur just use deformation mblur
