Procedural Penis Animations/Collision [Beta]

character's lower lip clips into her gums and teeth

This mod does not make characters' lips clip inward. That would be caused by another mod. So that issue isn't caused by this.

Anyway, set the hole position of the mouth in front of the mouth, so the penis follows a track that doesn't go through the lower lip, but between the lips.

An improvised fix is to set the teeth depth and oral depth to as far back as the sliders allow, in Racemenu. You can also reduce the size of the teeth, and set their height.

 

If the penis has SMP collisions, it has some SMP settings of it own, in its SMP config file.

You can try lowering the margins to 0.01, in the SKSE\Plugins\hdtSkinnedMeshConfigs folder, from the mod that is giving the penis SMP collisions.

I don't know why or how margins matter, but I did it, as it was recommended in the High Poly Head SMP topic, and it probably helped.

It would be nice if PPA would go disabled in FPP mode, especially for ABC, when it is on and you move your head it causes lil bit fuckery.

you can just hit F2 by default and disable it while in fpp

So what was the mod that was causing the problem for you? I also have that problem and cant seem to find a way to fix it.

Check your ABC installation, when you download it comes in zip, the zip have the 7z, not proud to say it happens to me once.

It was a bug caused by immersive equipment display extra skeleton nodes. I left a comment about it just in case someone else has the same bug.

Sorry if this has already been brought up, technically impossible, or is already implemented.

(or plain stupid, or if I'm making wrong assumptions)

 

But if not, would it be possible to let the penis enter the hole (i.e. connect to anchor bone) at a slightly relaxed angle?

 

Left side is my understanding of how it works currently. Dick always enters the hole (connects to the anchor bone) at a perpendicular angle. Relative angle of each item is always the same. This can sometimes result in an extremely bent dick.

 

Right side is what I'm proposing. If the angle difference of the hole and the dick is more than 0, dick would enter the hole at an angle (within a user defined limit), reducing the bend of the dick as a whole. I can imagine that this wouldn't always look good, but also it might make some scenes look better.

If this is possible, I think it would need separate config for each type of orifices (like most parameters in PPA already are), as well as separate angle limit for upward and downward bend.

ok, WOW
 

I just happened to get pointed to this mod and its GAMECHANGING!

 

So I just wanted to ask/add if "Penis Size" is planned to be recogized somehow?

A troll/Horse etc. should sound differently than humans.

Same for special anims with tentacles maybe? 

 

I also wanted to ask, if there is an API somewhere?
Is there a ModEvent I can scan for that would allow me to link sounds myself?

Like linking the moans to the thrusts, playing additional monster sound etc. or just time certain events with it, adjust stamina usage during sex, etc. etc.

And for future reference, just because this is already mind blowing:
Plans for Hands/FIngering? Hand Slapping? (Face, Butt, Boobs) or possible for ZAZ Whips hitting the body parts?

Girth config was a thing since forever. Supports race overrides too.

CornerSmoothing

Also to me some rigs (werewolf) look better with PreserveHavokState = true

Also also shitty angles and snapping dick can be caused by bad bones weights, as described in the OP.

Thanks. Will try tweaking the value.

Had anyone made a strap on that works well with this mod yet?

For sounds no. Mod events, doubt it because it would very likely overload the papyrus engine. For voice sounds you've got a pretty extensive system here that includes .lip support: 

There's no plans to extend the impact sounds, I'd recommend using Sexlab Sounds with this mod and just disabling it's thrust sounds.

Hello question, with blowjobs my character mouth is closed, but trying in another save it works. So it must be settings. What setting are used to have the mouth open

Ur face got corrupted. It happens.

It's usually caused by SMP corrupting the face from smp hair. It's fixed in the latest FSMP: https://github.com/DaymareOn/hdtSMP64/tags

 

You can use the PPA action menu to reset the actor's head

Thank you, opening the menu and selecting fix face expressions works, but only momentarily then reverts back to closed. Then I should wait for the upcoming update of FSMP

That said, since you're busy fixing everything sex-mod in skyrim... Do you think you could do something with the Khajit/Argonian tails during sex scenes? Cowgirl is mainly fine, missionary 'looks' fine since the tail is on the bottom clipping through the floor/bed/table etc but dayum, in almost all doggystyle anims the dude is straight up impaled while he is meant to be the one impaling the bird.

You might've already got an answer but if you haven't, the best way to solve this is either to install a no-tails mod or a mod that adds SMP collision to the tails. There's a few out there, mostly on Nexus. I prefer no tails since even with the physics and collision it's not perfect (way better than vanilla tho).

Yeah... No tails isn't really something I would consider and the smp tails don't 'wag' like a tail should, they just sort of flop around. If there was a way to activate their floppies just for sex scenes I would use the shit out of that though.

Hey is it at all possible for me to build a config to disable the mouth opening effects on the PC without removing it from the NPCs? Or is it just better to disable it and edit expressions in SL per scene because i get a ton of stretching and warping on Preds HPH even when i set the collision cylinder radius and height modifier super low. With it disabled his mod works perfectly but then obviously the NPCs just leave their mouths closed completely during scenes. I read the facial expression system tutorial so maybe i missed something or is it just not possible (I really dont know anything about creating/modifying files so thank you for making it so easy to understand and edit stuff)

Hello, I'm looking for a solution to this problem I'm having when using the Erin race. I don't know if there's a solution, and I'd appreciate it if anyone knows one. It only happens when I activate PPAs, and these are the only mods I have. It's a clean installation of both the game and mods.

Hello , the latest version doesn't work for me but the beta version works fine , I'm using the latest version of OSTIM , what might be the problem

Is there any way to turn down the moaning volume so that my wife doesn't file for divorce? 😂

Hi. First of all, thanks for your amazing mod.

 

I just wanted to mention that I've downloaded the latest version of FSMP, 3.1.9, after reading your comment and I've found that, at least in my modlist and only changing that update, your mod stops working, the dicks revert to being rigid sticks with no animation whatsoever. Switching back to Nexus version 2.5.1, everything works as it should.

Sorry for responding late, I only just now saw your comment. The other mod I had messing everything up was this one

Tried myself v3.2.2 & 3.2.3, got the same feeling. Like PPA stops working at all (tried with animations I am familiar with).
