Belly collision bug, help needed

[yevvie]

So for a few days now I've been trying to get belly collisions working to no success. I've read and tried everything pertaining to it I could find, tried a couple of my own random ideas, no dice. I'm now 100% clueless as to why it's not working, and if anyone has any ideas, send em my way. Probably worth mentioning that the dick goes through the head as well, but I'm not sure if there's any collision that addresses that.

 

Stuff I'm using that might be important in figuring out why it's not working:

• XPMSE
• 0Sex
• AIO Animated Pussy
• SoS + the female addition
• It's a custom follower built on UNP special, with all the needed xml files attached. The vagina moves, not perfectly because some poses don't line up properly since the other character isn't male, but that works fine for all intents and purposes.

Mine works fine so maybe try using this mod

http://www.nexusmods.com/skyrim/mods/72030/?

 

and follow every step it has for HDT working with vaginas

Theres also skin patches and a SOS patch at the very bottom in the download section, if you follow this it should work perfectly fine.

 

Just by reading the description alone has helped me figure out alot of HDT issues.

[yevvie]

The problem is, vaginas work perfectly fine, labia is animated, detects collision, looks like on Leyenda's pictures. Meshes are linked to proper xmls.

 

Tested on two computers with similar Skyrim setup, with 0Sex, with SexLab, with custom UUNP Special meshes, with default meshes packed in AIO Animated Pussy. With male schlong, with female schlong. Belly collision just doesn't work, no matter position there's no bulge, everything goes right through.

Tried with Havok object, didn't change collision.

Tried adjusting schlong with keybinds and other stuff, nothing works.

 

Any more ideas?

 

[SassaAria]

I'm still getting familiar with HDT as well, so I may be missing something or worse.

But maybe this will help in someway?

Or maybe prompt someone more knowledgeable ?

 

(1) Did you try role reversal where she has SOS UNP schlong, and your female character does not?  Just to see if it's an NPC or other issue?

(Assuming your PC has full HDT special body.)

 

(2) Looking at your 2 images to illustrate your described issue, it looks like you are expecting HDT belly node to re-route the schlong position?

Is this stated somewhere as a feature of HDT?

Whatever I read - it was always you still had to line things up ie. in this case, lining up schlong with Vag was still required.

So in your images you'd have to adjust both the schlong and maybe the body of either actress - up, down, forward, back.

Well, unless I missed an important detail about HDT. 

 

Also found in game that inorder to trigger HDT belly, also needed were:

(i) a schlong long enough to reach close to belly node (sometimes had to move privates closer together depending on anim), and

(ii) some positions are just much better in getting both vag-node and belly node triggered.

Some of the AIO gifs have the better positions. 

The type pf position in your images doesn't work well for me yet without merging the 2 actresses into each other a bit (haven't made time to try lots of schlong bending to hit (or get close enough) to trigger both nodes).

To see when node triggers and get an idea of distance involved - you could move the schlong/or body away from the vag and see when the vag closes?

 

I am using Floppy SOS (deselected the HDTdisable in MCM) with full SOS and UNP female add-on.

Do hope this helps and thank you for your various texture contributions

 

 

 

 

[yevvie]

Definitely appreciate the input. We tried role reversal, different characters, completely random NPC's with completely random characters, dicks of all sizes (not gonna lie I laughed typing that), still not even a twitch. For that particular position in 0Sex that was the best lineup I could get, or at least close to it, can't remember exactly. I know it was lined up well enough that the vagina reacted. I know the schlong is long enough to hit, and I had the idea that it was maybe a problem specific to 0Sex, but even with Sexlab it didn't work sadly. I'm also not aware of any way I can tweak positioning in 0Sex animations, but if there is one let me know.

 

Thanks again for the input, and I'm glad you like the textures.

(snippy)

Thanks again for the input, and I'm glad you like the textures.

 

Quality work is always appreciated.

"Dicks of all sizes" that does sound quirky-funny.

 

So with role reversal you can't get belly to react in the same position as AIO gifs?

Did you try a SOS UNP 13 to 16 size just to be sure in Sexlab anims (Osex has own schlong sizing that you can disable but not sure of the whole dynamics)  and was the schlong movement almost flat in profile from vag to belly along the flat horizontal length of the body?

It sounds like you did - but just want to make sure.

 

How do you manage your mods?

To test the issue, you could use Calientes Bodyslide and build one of the vanilla UUNP Special body mesh preset for your PC  where you know belly node is 100% included (different from your usual bodychoice - but maybe pick a more common bodymesh preset like 7B or basic UNP - it looks like you have a UUNP body).

Drop that in your loose files for your PC in the right folder and continue with role reversal.  Seems to me loose files are last in load order, so overwrite everything else (Do everything manual so never had to be sure of that detail)

Then maybe pick and test a few different missionary positions in Sexlab where the lining up is pretty easy and schlong profile is fairly well aligned all the way to tummy and lift the body up and down to see if it makes a difference.

May want to set SexLab anims to disable auto-change of phases if you don't already while doing your testing.

Downside of missionary, you have to peak in-between to see any tummy movement  .

 

As for Osex, sorry can't help there.  It's been a while.  Started with Osex and moved over to Sexlab.  Seems to me I did adjust the schlong for sure and also the body positions.  Check the hotkey assignments maybe? 

 

Oh and one idle animation that is really nice for testing the belly node is the one where the PC hands travel up the own waist to the breasts to cup them.

Along the way the hands brush and lift the tummy and lift it, and as the hands continue up the tummy drops down with a good bounce.

At least that way, you'll see the HDT belly node is working.

 

Another thought is maybe try another physics file?

I have been using the bounce and jiggles physics file from the link provided in the first responders with TBBP.

File size is 100k - so a fair bit larger than AIO version.

Maybe try the most exaggerated one first for testing?

[yevvie]

Yeah, no dice. Even with male PC no luck, cause first thought that SoS for females was the problem, but turned out nope. Tried basically every size of the UNP schlong, nothin, I have to keep 0Sex's scaling turned off, otherwise it ends up with a tree trunk between the characters legs, which though it's funny to look at doesn't really work well, tried default body with nothing changed, even the one Leyenda includes in the mod prebuilt, tried with one of his or her followers, all of those with both Sexlab and 0Sex, still nothing. Forgot to mention that I use MO, I made sure nothing that would be causing problems if it was overwritten is overwritten, so nothing wrong there. Tried a few different collision files, even double and triple checked that the belly collision was in there, no luck with that either. Even reinstalled XPMSE on the tiny chance that was the problem, but nope. Gonna go hunt down that idle and check, because I forgot about it, we'll see what happens with that.

Let me know if you can't find that idle.

That one right?

Download JFF (just for fun)

Open the JFF program and load up your hdtPhysicsExtensionsDefaultBBP.xml.

Double click on NPC belly. (NOT HDT belly)

At the bottom of the window that pops up make sure that box 0 isn't checked, if it is uncheck it and save.

 

 

If it is already clear then the xml your using isn't properly setup to enable belly collisions, try http://www.loverslab.com/topic/54417-naturalistic-hdt-jiggle-and-collisions-xml-set/page-4?do=findComment&comment=1626303 it works beautifully.

Your hunting was good

As you probably already figured out Animation 1 in that series.

In the mod-authors' GIF with the FOMOD, tummy does not move but breasts do.

My actresses flat tummy when naked lifts and bounces tummy very visibly.

 

Be happy to hear if tummy works with this.

 

Further to what Keyser wrote, I have zero box unchecked, and also 4, rest all checked, and group_id is 10 Body, undefined.

JFF is handy; previously used to change a KS HDT hairdo physics weighting very quick.

The more I test the more it seems like it's some problem with SoS for females. Far as I can tell the collisions are working fine, but it just refuses to react at all to female SoS. It seemed like it worked fine for males, but not 100% sure.

[SassaAria]

Sounds like you got that idle to work for tummy node test? 

 

F-npc uses SOS UNP on me.  Haven't tested other way yet in terms of tummy.

In some animations, there are times my tummy doesn't move at all.

Other times, like last night, while doing testing found a sexlab animation (on table in missionary) and tummy was really moving in one phase, much less so in other phases.  Lining up was absolutely critical for effect to happen. 

 

Just to check - neither of you has BodySlot 37 (feet) occupied with anything (mod Bodyslots is useful for this)? 

Slot 37 instantly disables tummy for me regardless if Heels (NIO or HDT) or just footwraps.

But gloved hands worked in my test.  Will have to investigate that in the next months.

 

Edit:  Just came across this.  Another item to check for possible physics glitchies.

After some more digging found out it's a conflict between Leyenda's mod and belly collisions (which was mentioned pretty obviously in one thread about belly collisions, just glazed over it), and you have to pick one or the other, they won't work together.

 

Sucks, but at least figured it out.

[shardoom]

Not true, Leyenda's mod comes with the naturalistic hdt.xml's as an option which definitely has belly collision.

[yevvie]

Seems to be true, I know the XML's he includes have it, but it doesn't work. Soon as I stopped using the mod, it started working. Even when I checked his followers they had no noticeable belly collision, so I'm inclined to believe that's the case until I find proof otherwise.

[shardoom]

Well whatever works for you I suppose, all I can say is it works. Since it's the one I use.

I actually requested a modified xml in his thread (naturalistic xml thread) because I didn't like it, feel free to read through his page. *shrug*

[SassaAria]

Soon as I stopped using the mod, it started working.

 

Happy to hear it's working for you again.
