Hi there!

For some reason the vellum weld node completely freezes houdini if I'm using a voronoi fracture (interior surfaces disabled) to split up my cloth before sim. Edge fractures seem to work fine. It seems the "add bend constraints" vop within the Vellum Weld node is the culprit.

Is there anything I can do to prep the geo before going into Vellum that will fix this? I quite prefer the look of the voronoi fracture compared to what edge fracture produces.

Thanks!

I created an example file to illustrate the issue-- notice that if you enable the vellum weld SOP, Houdini freezes while processing the "add_bend_constraints3" node within the subnetwork. If you disable "Add Bend across Welds", it won't freeze, but then the sim looks really wonky.

It seems that if the input geo has lower polys-- the issue doesn't occur. I'm not sure exactly what that margin is but it's too low for the kind of look I'm aiming for.

Any ideas?
