Vellum Drape has an option to set since which frame the welding takes effect. But I found no matter which frame I set it to, welding always causes a lot of artifacts because it's so fast. The points can move across a long distance at that welding frame.

Is it possible to "weld over time"? For example weld some points at frame 1, some others at frame 2. Or making welding work like a distance along edge constraint whose rest length gradually decreases.

you can time welding points as you want but that will not change the fact that the act of welding makes the points snap together

what Vellum Drape is actually doing when weld is enabled
is doing stitch constraints first that are pulling seams together with no gravity until the weld frame
and the idea is to weld at frame where the seams are already almost touching
at weld frame seams are welded and gravity is turned on
so it should be already doing what you are describing (the restlength thing) but maybe you just need to allow for more time for seams to get closer together (you can uncheck Freeze At Frame to see the process during playback)


you can also apply the same logic to welding overall not even for drape if you are willing to set that up, but that's the basic idea
make sure you pull the points together first before you weld

Interesting... maybe I other constraints are too stiff so they don't get closer fast enough. Thank for the reply. I'll experiment more.

Did you find a solution so far im still wondering and searching the solution for it.
