Hmm, okay then. I thought it is the very same thing, looks similar. Of course it is a general circumstance that can have different consequences - i had the hip doing it alone on multiple occasions. It is "just" the thing how VaM achieves its physics i would say. And you don't need plugins, these are VaM core settings, the plugins just make it easier to manage them.
Yes, I also think that this is all general connected to on how VaM achieves its physics.
I just have to deal most with that hip situation, but you supposedly know this problem only too well

Plugins sure can help on some things, but as long as I can solve it somehow without them, I prefer that way.
But sure, If you cant fix it otherways and a plugin can, then sure use that Plugin.
I also found this thread here:
Hi, I am new to virt-a-mate. When I try to pose models, sometimes they end up erratically jiggling/spazzing out of control. I tried turning on and off collision of the model, but it didn't work. Does anyone know how to fix this? This happens often when trying to make tight poses where different...

It seems to be the same general topic, regarding "jiggling", and the following statement by TToby seems to describe it quite well, especially imagining a rubber leash:
"Hi, this is unfortunately a common issue. There are forces between the different body joints, like a rubber leash.
If you draw away the points too far, this may spazzing out. On the other hand, you have the collision and physics that can go mad."
Yes, sure a good thing to not to draw the points too far away from they're original position...
This will definitely cause fewer problems.
If you just had that one occurence, may be it was something special. I have these problems all the time, sadly, alone today ~5 times. -.- I think it is because i don't know/understand the node interactions completely. Time to "git gud" for me

Thanks for your answer.
Ah... no, it's not just once, that hip thing happens alle the time.
But when I then fix the positions again, it remains more or less stalbe.
I also don't understand those physics and node interactions very deeply.
It seems to be a really complex thing.
So it is always helpful, to get some good inputs to learn a bit more about that topic.
