Sloshy Breast Physics?

Recommended Posts

I've been messing around with my breast physics for over an hour, but I can't seem to get them the way I want. They're close, but not quite.  

For starters, I'm using SN Venus Gaea Breasts. What I want is for them to "slosh" when I'm walking. Since they're very large and have a natural look, if at all possible I would want them to look very fluid and soft. If a reference would help, Hitomi Tanaka would be accurate to what I'm trying to achieve with the breast physics.  

I've mostly gotten them to perfectly do what I want when standing still, but oddly enough when I'm walking, they sway but simply don't bounce.

Here's what I have so far:

 

Breast Bounce:  

Max Effect 50

Spring 31

Gain 85

Damping 74

 

Breast Cleavage: 

Max Effect 20

Spring 17

Gain 22

Damping 42

 

Breasts Sway:  

Max Effect 30

Spring 23

Gain 14

Damping 42

 

Advanced Parameters:  

Mass 70

Gravity 0

Drag 77

Tried four different AOs with varying walk animations, it still simply doesn't seem to affect the physics as much when walking as it does when standing.  

I do have the physics setting on max, and I've tried messing with the slider just to "reset" the physics once in awhile.

   I honestly see the least bounce effect when walking regardless of the magnitude settings. With the settings you describe, you're likely to see little bounce effect while walking because most walking animations don't provide a lot of Z axis movement, but an exaggerated effect, perhaps excessively so, when, for example, ascending or descending stairs, or other, more athletic activities that do produce significant Z axis movement, or when your avatar is animated in various ways while prone, or in other non-Z axis orientations.

   Try some vigorous dances with the settings you have and see what results you get. Maybe it's just me and my experiences, but walking doesn't really seem demonstrative of the avatar physics bounce effects.

The main problem I'm having is it's rediculously difficult to see the changes while editing the physics. For example, I can turn up the spring a huge amount and see no difference, but then when I turn the physics slider setting up and down, it goes crazy.

From what you describe, and from looking at the numbers I would say that you're negating much of the natural bounce by having weights too high and the spring timings too low. A Mass of 70 is HEAVY, and so takes a lot of movement and impact to get to even the smallest jiggle/slosh.. try lowering that by half. Spring timings won't show much at all when Drag is over like 10%...Try to set the rest of the settings with drag at 0%, then add it if you have to as the very last step. Spring isn't how bouncy they are, it's how long it takes for your bounce to.. bounce and come back. If it's too low (or drag is too high), the motion will get lost in the next movement (a.k.a helium t*ts)... try 70% or more. Gravity is your friend.. it amplifies the "weightiness" in a good way and is crucial to getting that slosh you're after.. best guess is 20 - 40%. Dampening should be kept high.. a movements 'second coming' should never be any where near as strong as the first unless you want 'golfball in a sandwich bag' boobs. Gain is the percentage of ALL movements (tiny and huge combined) that you want to be maximum boob flops... realistically not very many normal movements are black eyes. Keeping gain in the bottom third of the slider will also accentuate all the smaller motions that exist between none and 100%. And finally, fitmesh addons and clothing usually don't have the same physics as the default AV. You will need to tweak the settings often.
