Well, I would start here:
"<Breast_Spring>20</Breast_Spring><Breast_Dampening>0.98</Breast_Dampening>
Thats level 1 bouncyness. Breast Spring controls how soft the breasts are and Breast_Dampening controls how much they will bounce before comeing to a stop. Level 2 is 0.995 Breast Dampening and level 3 is 1 in Breast Dampeneing."
What program are you using? I use notepad++ because of a few reasons, one of which is the option to find and replace, so I would find
<Breast_Spring>20</Breast_Spring>
and replace it with
<Breast_Spring>10</Breast_Spring>
or use a different value. And then do the same with:
<Breast_Dampening>0.98</Breast_Dampening>
Now, if the values are different then just search for </Breast_Spring>, and change the value in front of it. And then keep manually searching through. Yeah, it can take a while this way, but if it needs to done, then it needs to be done.
