VaM 1.x Collider problem? (Mini-giantess animation)

[TallGirlEnjoyer]

Trying to create some futa giantess scenes once again but VaM is really making me frustrated.
Once i'm about to create shapekeys and start the actual animation process I always end up with things vibrating/shake like this and I don't know what to do, Im not even straining the limbs and the models do not have that big of a size difference.
It's a matter of colliders, right? So how do I fix this?

It almost always comes to this. As soon as one of the characters tries to touch the other it starts to vibrate. What am I missing?
It's almost pathetic from my end that I can't even animate a simple handjob scene. I'm ashamed.

I've asked a related question before when it comes to giantess scenes, and that it is very hard for the physics when it comes to size-stuff, but if KittyMocap, Anubis, Azur and DreamVRX can do it then so can I, lol...

That's not even remotely "vibrating" when it's THAT discreet, I had to playback the video three times to actually realize what it was showing xD

You will have problem with scales, no matter what you do. But a couple of pointers :

• Loosen the grips. Nice looking contact are often just faked well enough, you can't really hope to actually "grip" something and not end up having collision jitters
• Tweak friction for all characters to 0 to reduce this to a maximum
• Eventually tweak colliders but this is generally a nightmare and is simply compensating for the grip (so loosen the grip is pretty much the same approach)

If "people can do it", it also maybe is just time and refining and "thinking out of the box"
