How you adjust it
Nothing here is baked in. Every value stays live on the object for as long as the file exists, so you can come back and retune it, reorder it against other effects, or take it off and get your original path back exactly as you drew it.
This one has no panel controls at all. It is shaped entirely by dragging its handles on the artwork, which is why it has none to list.
