Been trying to figure this one out here for a bit. If you have a mesh, say a sphere, and set it up with an edge fracture on the original topo, then create a remeshed sim ready version, execute your vellum tearing sim. Is there a way to get the original topo WITH the edgefracture seams to deform properly with the sim version. I have tried point deforming with utilizing the piece attrib, that does work BUT it also does not retain any stitching at all. You either get all the pieces following correctly or following but not properly separated at the correct edges. Just curious if anyone has solved this challenge.

I had this problem. my issue was the points on either side of a tear didn't match up. you have to do the fracture AFTER you make the remesh. OR you use Marvelous Designer with pre-fractured pieces as the points always match up. When they always match up you can ensure perfect tangency in both the point deformed sim-to-hires.

you could also use vellum weld constraint to marry the edges in the hires on just the points you want to match up.

interesting, i was figuring i'd do the edge fracture prior to the remesh so that I have the fracture pieces at least matching in both the pre-remesh and remeshed object. I'll take a look at using the weld to "fuse" the edges on the highres post sim and see what that gets me.

Thank you for the info

as it turns out I'm doing a slicing sim now and I ended up going with Marvelous Designer to create the tears instead of edge fracture. It gives super even edges you can define with internal lines that are evenly spaced and exactly on top of each other so when you add the vellum weld constraint it automatically welds everything together.
