Hey I use UBE  Futa Female character... Although the physics are there , there are some inconveniences naming the Size of the Futa genitals , 

 

Maybe its me that do not understand how to tweak the  config file , but the bending either goes to up front of the genitals or its just the Size that can't be bigger than some size ..

 Part of the problem is that The Futa penis bends to upfront !  Don't know where to change that in the ini .

 

 

UBE penis is offset by default. You need to go into bodyslide, and build a UBE penis with the height set to 100%.

If you had 0.0.16 instead of 0.0.16B - it was bugged.

I was really hoping to fix jittering CBPC belly bulge caused by overpenetration using this ClipFix of yours. I mean, it's kinda working, but shlong nodes are removed abruptly, causing noticable (what an irony) belly jitter. Lol.

I think you forgot to remove SolverDynamic pieces of code from ABC patch.

 

I came to conclusion that PreserveSchlongHavokState is essential on large shlongs. Without it it makes shlongs spear looking, very thin and long. At least on my config.

Loving the mod, great work and support.

 

One of the known weaknesses is for when the mod is trying to assign positions in multi-penetrator scenarios...  ie, crossing streams in multiple pen, or fighting over the same hole when not expected.  It's all a matter of limited info in tags.

 

Obviously your mod IS reading tags, and this works well in single/spitroast situations, unless a sequence is using both anal/vag, or is otherwise mistagged. 

 

I'm not sure if you've looked at Hentairim?  The mod has a really well fleshed out tagging system for audio/expressions, amongst other things.  The tagging system itself would really work well with your mod, if you made it aware of its tagging system.  It is set up to tag the situation on a per-scene and per-actor basis.  So for THIS mod, it would know that Actor 2 should be in the vag, Actor 3 should be in the butt for Scene 3, but perhaps sharing Vag or butt for scene 4. 

 

Use of the tags themselves does NOT require the rest of the mod system.

 

Tags are applied via SLATE (I think P+ applies them differently though..?).  Just the scene tags would be needed for this mod, not the sound effect tags.  Not EVERY animation or pack has tags set up, but the majority are.  There is an SE/AE version, and a P+ version.  The tags are the same between the two, but the P+ mod page has the most up-to-date tags.

 

Not sure how difficult or desired it would be to make your mod hentairim tag aware, but it may have some value looking at.

I have bug on 0.16 version with humans and cteatures. Pussy  and anus work on this version varied too. On version 0.14 all work fine.

I don't know what you're saying. Speak in your native language and be very specific so I'll be able to reproduce the problem. Я не понимаю, что вы говорите. Пожалуйста, пишите на своём родном языке и будьте очень конкретны, чтобы я мог воспроизвести проблему

 

Make sure you're using the ABC mod too, and that NastyCritters doesn't override it's files.

There's going to be an annotated animation system soon that will correct all these issues. Just need to get everything else in order before adding more features.

Sounds good.  Just wanted to pass along that there is a tool available that could be useful.  :)

From the perspective of a very straight forward/basic user of adult mods the 0.16 release is superb. The new bending system is excellent. 

[Moonpaw]

Im having smp crash when using this and when removing devious device restrictive boots. Does anyone know whats wrong? Im using 3ba and fsmp

There is ONE bug with it due to a minor math error. But you'll only notice it during really offset animations.

I douuubt this mod is causing your crash. If you produce me a crashlog from https://www.nexusmods.com/skyrimspecialedition/mods/59818 then I can most likely see the exact reason you're crashing though. Make sure FSMP is fully up to date, and not a non-avx version (That version is designed for SUPER old processors). 

 

 

[asdt123123]

Here's another pre-release if anyone wants to test/give feedback. 

 

Currently battling over an issue with very offset older animations overshooting. Like the whole base/part of the pelvis goes straight through the hole lol. If anyone's interested, or maybe has a lot of math experience + a better idea - My original code (0.0.16) was detecting this overshoot using the dot product of the base->hole. However that proved problematic since some of these offset animations can have virtually parallel sex positions. Second idea was euclidean distance with dot product correction - still not perfect. Last one I stuck with is classification based on the actual arc - which seems perfect so far..?  Anyways, that's why I'm constantly popping out updates, the math gets really convoluted the more offset the animation gets.. 

 

Changelog: 

• Shouldn't have anymore blatant issues with very offset animations anymore (Extremely offset will always have trouble obviously)
• "MinProjectionDistance" in the config existed in the previous version, but basically it sets a minimum distance your penis base should be kept outside the body. Sort of creating a visual collision (Like the penis base bumps into the hole, can't go further in). 0 by default
• "RotatePenisBase" added to the config. Some creatures have vertex painting that significantly influences the testicles during base rotations. So you can toggle it off now to help restore the testicle appearance a bit. Some may prefer this for humans too.

Tried version 0.0.17.

No doubt the schlong has been improved and Doggy Style looks a lot better.

But at the same time I am missing those violent bends that made it look savage.

Never the less I am seeing improvements in every version. Keep up the great work.


For the time being I am staying at 0.0.9.

Версия 0.0.14 - все работает без проблем. В новой версии 0.0.16 появились баги как на скриншоте. Пенис (и у существ, и у людей) выворачивается в противоположную сторону, если его кончик приближается к влагалищу, анусу, рту. Но при этом сама физика открытия отверстий срабатывает.

На всякий случай, ты точно 0.0.16B скачал? Архив 0.0.16 был испорчен.

Got another snapshot release for 0.0.17 with more changes.

 

Changelog:

• Added some very simple compression/decompression animation to the penis. Probably wont be very noticeable, just looks a bit more natural.  "PreserveSchlongHavokState" overrides this behavior 
• Made improvements to "PreserveSchlongHavokState" to insure the penis follows the animators intent better. 
• Smoothed out some animations 
• Improved the deep throat animations more for more rough animations (Also fixes a bug with huge ass schlongs)
• "SolverBendConeBase" is now deprecated. It will effect the animation, but I don't recommend using it since the base logic already biases a stiffer penis. 

 

Animations should be more fluid now with the penis. I doubt it was very noticeable unless you were staring at it to begin with, but I figured there was room for improvement. The only time you'll notice little micro jitters is from when the base of the penis goes completely past the vagina/etc. This can be smoothed out more too, but I didn't bother since you can't even see the penis at this point unless you're xraying the body. 

 

Lmk if it works well. If there's no more issues, and all the animations look SOLID I'll move onto the animation annotations next. Which will properly tell the schlong it's job during animation stages per actor.

This mod is absolutely revolutionary! I can see it becoming staple in any NSFW modlist. And thank you for the ostim compatibility, works like a charm. But I noticed it doesn't work with creature PPs with OCreatures. Tested with wolf, horse and troll, as you mentioned confirming these work, and werewolves and giants. Attached log just in case

Hey I was wondering will this mod work with maars/Samvagina SE (it's a sam equipable vagina, to view mod in game type help vagina in command menu to view code then type player.additem to obtain) if so how would AccuratePenetration be merged into this mod or would anyone be willing to merge it?

Unfortunately that mod may not be adding the actions correctly to the scene. Or creatures have completely different actions like "doganalsex", etc. 

This mod checks for "vaginalsex", "analsex", "blowjob" on OStim. If you know a way to view the active actions in OStim, you could help me add support for that mod though. I don't have enough time to test it myself though.

This mod can work with anything if you're willing to do the configuration for it. Review the config section.

I'm assuming you're gluing a pussy on a male actor. So you'll need to make an override config with a MALE predicate and give it the proper offsets for his/her? holes. You'll also need to disable "IgnoreMaleActors" in the male confg.

I just wanted to stop by and say that this is some amazing work! Thank you so much for sharing!

Some animations were not inserted, and after using this mod, distorted insertion animations will appear.

[Legend0fJan]

Awesome updates to an alraedy insanely good mod!

Since you will be tackling animation-based changes for the coming releases, do you think it's possible to add a toggle for vaginal/anal penetration that overrides the SLAL tags?

[Hyacreap]

dick will swap positions where they should be in some DP scene

for example, when dodgy DP scene play, the top guy's dick will go into vagina, and the bottom guy's dick goes into anal.

Turn on the visual debug options in the config, and produce a video/gif so we can visualize the problem. 99% of the time, distorted insertion is due to the forward vector being incorrect. Which would only be the case if you're using a very odd schlong.

Yeah there's going to be another hotkey you can use while pointing at an actor to change his "intent". Wont be using SLAL tags, rather it's own config.

Technically yeah, but that's 1 more framework the mod would have to poll every second. If that Dogma guy is interested, I could add papyrus API for initializing a scene. Would just be something like PPA.RegisterScene(mainActor, PenetratorActors[], Tags[]). Then PPA.DestroyScene(mainActor). etc. 

Sorry saw this in my notifs a whole 10 days late. I reached out to him and asked, but out of personal curiosity, what would the addition for the API mean? Mb I'm not that familiar with these coding stuff
