Ah thanks. Right. A magnet is a like a JCM but its applicable to entities nearby. Yes, that makes sense. But do magnets work when join centers are moving? That is a good question. You say it works better when these poses are active? Does that depend on the cloth? That magnets make things more complicated I think. Weird. Yes, that would be interesting how V4WM performs compared to V4. I wonder why the magnets do not totally break the V4 when it gets morphed towards K4.

Btw, the script converts V4 or M4 to weightmaps in the first step anyway. So it has to work for V4WM in one way or the other.
