I'm rambling, but in case this helps someone: set 'simulation quality' in FSMP fairly high.

I made some changes to FSMP's solver settings some days ago. Afterwards, in all SMP collisions, the collision meshes would 'collapse' into each other.

I set all limits in the SMP .xml to 0, but it was still happening. I was about to lose my mind.

So I looked at FSMP's settings, and I discovered in the FSMP MCM that I had set 'simulation quality' to the lowest value.

I set it to the highest value, which immediately fixed the issue.

Hi, the default value of 16 is alredy good, if you better try 32, but this value can have a cost in the SMP "time", so dont go crazy in it.... default 16 is good, if you have spare PC horse power, try 32.

this is on a fresh save, i recently updated from an older version which didn't have this issue.


 

Hi, hmmmm looks like collision problem with another mod or the body collision itself, or somehow race menu is using the sliders i made for PPA with the throat bulge, try installing wihthout them just to check, if not it, good!!!  it is another mod collision messing with it and you can install them back.

I tried reinstalling your mod, this time unchecking the "bodyslide support HPH 1.4" option which seems to have fixed it. idk how it worked seeing as i didn't touch the bodyslide project in my initial install but i'm not gonna complain.

Hi, you seem new to modding XD, but this mod SMP head wont replaec anything about XPMSSE - XP32, now PPA yes, since it has a FIX for the XP32, so "FIX = Let it replace", i dont know about CBPC anus or anything else, PPA i know the fix works, since i asked and tested about it ; )

Thanks!

would it be a safe guess to say this doesn't apply to any of the beast races?

Hi, more or less, there will be usually a smal space in thre, you can see in the gifs sometimes, but a large one idicates that your XML for the penis collsion might have a large margin, you can just reduce it to 0.1 or better 0.05

Thanks for responding.
Not sure what XML are we talking about here. Is it the one I downloaded 'TNG_Himbo_SMP_XMLs', or in this mod, or some other place?

Only female "human" races.

Hi, if you using my XML, assuming is replaced the original one from TNG and Himbo, maybe the mouth of the character is opening too much try in sex lab to reduce the open mouth value in the expressions tab fro0 80% to like 50% or you have PPA and didnt install the PPA part of the mod, or also like i said there will be a small gap, not big, but small sometimes.

Yes, the SMP .xml of the penis somewhere in that patch will have a '<margin>0.05</margin>' line, with some value. supposedly you can set down the value.

but honestly, FSMP's settings and presets set to low can also cause issues, so try different FSMP presets and settings.

The High poly head's .xml settings also determines how the head's collisions behave, so that could also be tuned to achieve more stable collisions.

my old issue with the neck bulge is fixed but now i've got another bug. the lips aren't stretching wide during blowjob animations.

 

Spoiler

Edit: Forgot to mention this which is probably important, i'm using SOS. not HIMBO or TNG.

I have the same problem, but I use TNG and Himbo.

It seems like most comments ask the same handful of questions. The mod page should explain installation in a foolproof way, and answer all the frequently asked questions. Maybe in the style of the OStim Standalone Installation Guide, which is full of useful variations of setups, and caveats and issues to beware. The guide generally seemed rock solid.

I’ve managed to figure out what was causing the lump on the neck, in my case it was because the blue-marked line was missing. Now I just need to find out what’s causing the problem with the mouth.

I have it now, issue fixed and lips work as intended. 

On a related note, this file is very easy to miss as i skipped over the link for it on the front page.

Hopefully someone here can help me with this issue. Currently the mouth is not opening properly on the player when delivering BJs. I have had this working in the past but with the various updates to mods something seems to have broken with this and I can't figure out why.

 

Here is a couple of screenshots from two different animations showing the issue. I have seen it on all the BJ animations I have tested so far:

 

 

 

I should have the latest versions of all the pertinent files below is a snap of the relevant mods and their MO2 load order:
 

 

I am pretty sure PPA is not the issue as everything is lined up. I should have smp collisions... what am I doing wrong? Help!!

You should check if you have the exact same files from front page of this mod, this exact files: SOS SMP patch by Bakafactory posted by GusCrow

Also, in my game i noticed that if the NPC use SchlongsOfSkyrim and the schlong size is too big, it doesnt translate well when colision is in question. So try lovering the NPC schlong to about "4" or "5" in the SoS menu and see if things get better. With the Bakafactory patch of course.

Also, enable Predator HipolyHead smp and use correct head part from Racemenu maybe, im not sure.

If you've updated to the latest version of PPA, your PPA settings and presets will probably have been reset to default. Which is a bummer if you didn't keep the old version's config file, but if the preset wasn't complicated, just make another preset.

The latest version of HPH SMP also includes an overlay/override config for PPA, but I don't think this is automatically enabled, you have to select it in PPA presets. That too comes with its default settings.

 

Edit: the PPA expression config in this mod is enabled by default because it has a higher priority than the default PPA config.

PPA can apply expressions, HPH SMP cannot. I think HPH SMP only applies physics to lips, cheeks, throat and a few other bones, much like breast physics, that just fall and wiggle around in some constraint limit.

HPH SMP can make the lips drop and 'fall' around, but it cannot open the jaw by applying expressions or phonemes to the face.

But PPA can control expressions.

So you should read the PPA configuration guide, as that's a different mod.

Do I need the SOS SMP patch if I am only using TNG? I already have the TNG_Himbo_SMP installed as shown.

Hmm

 

When I had this running before the only edits I made to the accurate-penetration.toml file where I adjusted the "hook" value. With this current issue I have experimented with this value at both 0 and 2 and it seems to make no difference. I looked through all the settings in there is there another setting that needs adjusting there?

thats why i said in there (literal comment above the line) that you just "copy and paste" one of them and edit the mesh name....

Hi, well pics show 3 possible things, poor alingment or the animation started with crazy rotations and mouth is not where is should be, second it looks like collisions are messed up, so penis or SMP fixes is not  working somehow, and or the mouth of your character is not opening at all how it should, and that is not with my mod at all, my does not control the mouth opening.
