I've been having issues with the CBBE 3BA the left breast is always either twitchy, moving on it's own, or sagging during animations that do not affect that area.   Even when an npc is just standing nude her left breast twitch and moves.  I never had this problem with the BHUNP body and I just started using MO2 but I never had this problem with Vortex.  I don't want to revert to BHUNP or Vortex since I fully committed to 3BA and MO2.

 

This is the order I have 3ba setup in the left pane of MO2.

CBBE

CBPC

Faster HDT-SMP

CBBE 3BA

XP32 Skeleton

 

Has anyone had this problem before and if so how did you fix it?

Assuming then that this is not a conflict of SMP and CBPC trying to control the same node, the remaining options are:

  1. You have more than one SMP physics preset controlling the same node, causing what I call ghost forces. These usually show up as rapid twitching or the affected node getting a force applied to it for seemingly no reason.
  2. Twitching can also be caused by stiffness settings being too high for the current damping values. Increase damping until the twitching stops.
  3. Stretching, or sagging, can be caused by stiffness settings being too low for linear and/or angular limits.
  4. Edit: You may also want to look at COG offsets, as a high gravity coefficient might be twisting the bones out of shape if the COG is far enough. Think leverage.

Thank you for the reply but I don't understand what you mean by setting the stiffness or COG offsets.  Where do I access any of that?
