3BA SMP physic delay

[3LVN]

I got this weird delay on the body physic most notably on the breast and thigh where the node just lag behind by 1 frame. When jump or do sharp turn the breast node lag behind for a little bit and the thigh jiggle doesn't match the 3ba armor jiggle (the armor do bounce with the body but the body lag behind and it cause clipping).

The thigh clipping is caused by slightly differently weightpainted polygons, or polygons that are too close to eachother. Dunno about the tits, that just looks like a bad physics config to me.

I found this post with nearly identical problem but I don't know what the answer is about.

regarding the comment about HDT-SMP, it's a bit outdated, having been superseded by FSMP, so I'd weigh that into whatever you glean

 

And the issue outlined in that linked post has a very sundry answer.

 

CBPC and SMP handle breasts (And afaik, any and all "wubba" nodes) gravity differently. When you change from CBPC mode into SMP mode - eg using the 3BA hotkey, AND depending on the CBPC settings you're using, AND without any customization of the associated SMP XML for the player body, node accelerations are different between the two physics handlers (ie code)

 

That it sags slightly when SMP is enabled is, afaik, because by default, SMP has a slightly weightier 'gravity' susceptibility (how it works in my game for four different female players anyway) Or, if I didn't see your post right and for you it's sagging more when CBPC is enabled, effectively the same thing in reverse. Either way, they're different, and that's the point.

 

tbh, and wadr, I'm not quite sure what the problem is, if that's all it is. If the breasts are sagging into the ground or through your back, well, then you have a problem, but a little change in how the wubba is handled when swapping between cbpc and smp should (imo) be expected, since their defining programming code is different from one another. To remedy any disparity between their acceleration profiles, I suppose (conceptually anyway) that you could bone up on customizing both CBPC and SMP configurations for the player, and then "tune" the performance deviations out, at least to whatever limit is possible between the two physics handlers, using the CBPC configs, the SMP configs, or both. 

 

oh, and if your breast are sagging to the ground or through your back...it's likely one of two things (ime). Skeleton or FSMP.

 

good luck

The weird thing is that the left tit seems to be fine, so that makes the skeleton option unlikely I'd say.

Thanks for the answer. I forgot to mention that when falling down or turning, the nipple is the last part to follow the movement. On the image above you can clearly see that the nipple stay behind and did not follow the body rotation.

Both are like that, the left nip is sunken into the body.

That's a configuration problem then. First thing that sticks out is that your game seems to be running at 47 fps in an indoor location. Physics (and modern games in general) seem to all be bound to fps. Same reason why you get flying cheese in Skyrim at >60 fps and why there's massive user input lag in all games when fps drops. It's a beginner mistake if you ask me, but definitely also the easier way to do things. Anyhow, other things that I have documented as having an effect on motion speed:

1. configs.xml
   1. solver.numIterations
   2. solver.min-fps (uncertain)
2. Bones
   1. mass
   2. inertia
   3. *Damping
3. Generic Constraints
   1. *Stiffness

Adjust some values and see what you get. I can't remember if there's a way to reload the config in-game like there is in CBPC. If smp reset doesn't do it, changing cells or loading a save should.

I think kinda sorted it out, My FSMP config is set to 5 bones so the last two bone of the nip is on the next calculation, when is switch to a different config preset the boobs don't sag as much and flail around anymore. And the fps still stay the same.

Just out of curiosity, where did this come from? What states that there is N number of bones being calcualted (per frame presumably), and can it be changed?

Reread the preset, i was mistaken for number of actors for bones. But the different config preset works.
