BeeingFemale - Pregnancy Belly seems to be pressed downwards

[NCK30]

I am using CBPC for all movement and collisions.

I have BeeingFemale and Baka Fill her Up installed. Both could be competing for the belly node.

I also tried building the body again with "Build Morphs" enabled in Bodyslide.

I tried adjusting collision with the CBPC belly. No effect at all.


Here is a picture. The belly gets a little larger but seems to grow downwards instead of out.

 

I swear Belly physics in SE is a science. Might be easier to invent Warp Drive.

It looks like you selected "more physics" for the breasts in the CBPC installer, which adds a "more natural" gravity to the body, but what I don't understand is why it's being applied to the belly. Are you using CBPC only for body physics or are you mixing it with SMP?

That's what SLIF was made for. But this is unrelated to your current problem.

Why have physics enabled when debugging a problem like this? Disable CBPC and SMP and test again.

Initially I installed it with SMP on the breasts and CBPC on the rest.

 

I think I chose the more physics for weight 100 and less for weight 0 preset. But I have edited it a lot since

 

SMP did not work well for me and CBPC collisions were too good to drop.

I still use SMP on clothes and hair.

 

 

So I edited my CBPC files to perfection. Or so I thought. Collisions are great and fits my body well.

 

But that damn belly is impossible to get right.

 

Then I get a couple of NPC's pregnant and this is the belly. Does not look like it should and how it did in LE.

 

 

Traison mentioned another time that 3BA/BHUNP has 2 belly nodes or something like that. That is what is making the belly so hard to get right.

 

It's like it retracts when the male thrusts and is pushed out when the male retracts. It should be reversed.

You mentioned another time that 3BA/BHUNP has a wonky belly. Something with 2 nodes that You fixed yourself.

 

I have managed to get the "spazzing out" to a minimum.

 

And belly collisions do work with some anims. Not so well with others.


How do I disable both SMP and CBPC. Must I uninstall them to do that?

Yeah there's a bug in CBPC where the belly collides twice. The side-effect of that is that the belly bulge effect has a tendency to not go straight out but rather a bit to the side, or that it spazzes more than it should. Not what you're seeing here.

 

Your issue is most likely one of the following:

1. Linear Z or rotational X stiffness is too low to counter gravity.
2. Linear Z or rotational X min/max values are too high.

...and I'm leaning more towards the linear values.

Sort of. Find their dll files and rename them, or move them elsewhere temporarily:

cbp.dll -> cbp.banana

hdtSMP64.dll -> hdtSMP64.sock

 

Imagination is the limit here.

Well the pregnancy itself is working. Lydia just had my child. A black haired Nord.

 

No neckseams/black head or discoloration. 

 

I will try messing with the Linear Z / rotational X stiffness the next time I get somebody pregnant.

 

 

I was actually more interested in solving my belly issue. It does move to the side mostly instead of straight.

 

How would You propose to solve that?

Are you saying disabling CBPC and/or SMP dlls didn't fix the sagging belly?

I only have a workaround for that. It's a 1 line edit in the CBPC source code if I remember correctly. If you got the infrastructure to compile the dll, I'll go look up what the edit is.

I don't think I do. I assume it is cbp.dll

I use version 1.6.4

 

If it's a dll could I not send my dll to You? - Or easier yet use the one You use?

The one I use has lots of edits beyond this one simple fix. It would require you to remake your CBPC physics presets, and it may contain things that only make sense for my own character. You'd also have to edit SLIF to make use of all of its features.

Bytecode patching is most likely not a viable option here. Typically there's no free space left by compilers. A code cave would have to be found within range of a jmp from the patch location.

It does not appear that the source code for 1.6.4 is available. If you find it, I'll build a custom version for you.

 

Edit: Based on the changelog, unless you're on the GOG version, there's no reason to use 1.6.4.

 

Edit again: Also none of this has anything to do with the issue in the picture in your OP.
