Animated Gaping Holes

INTERESTING. That basically confirms the frame hook is NOT getting called. 

 

Which is odd because @Herowynne claimed they had 1.5.97 too and it works for them. 

 

Likely another mod is clashing with my hook. Shouldn't be a problem, I'll look for another spot to hook. Surprised this didn't lead to a CTD 

 

Thanks for the debugging efforts! 

 

Thanks for the quick replys !

Yes, that is correct. I am using SE 1.5.97 and regular Sexlab (not P+) and 3BA body and CBPC and Faster HDT-SMP.

 

I use CBPC for body physics. The Faster HDT-SMP is just for hair and cloth physics.

 

I tested using Public Whore in order to get a bunch of sex scenes. In my testing, the animated gaping ended fairly quickly, so I had to move the camera around quickly in order to see it.

Yup it's currently planned. I actually wasn't aware CBPC has mod events for penetration, so I'm going to see how accurate that is. That would avoid having to do cell scans constantly for potential candidates

 Can confirm that this version works in 1.5.97. Thanks!

Now it works here too. Thanks!

I love the concept. I'm currently playing a standard "Male" character, but would love something that works for NPCs.

Yeah this was just a quick proof of concept. Going to expand it right after I finish my "Player Slavery Scenarios" mod. 

 

Lmk if you guys experience any bugs. 

[gamerpk2]

thank u for the mod

simple and works as intended ^^

anything bad would happen if i used negative values ?

Make this log file spam stop, debug logging is disabled but still happens.

Fuck I must have left that debug code in. 

 

Btw that low of a delta is like fucking 800 fps. How did you mange that lol. Hopefully the hook didn't install on the actor update tick...

Here's a full log file, since you're curious.

Just a normal 30~ min game session.

All game play/menus are capped at 60 fps.

Except for system/journal menus, which is capped at 800 fps, and console, which is capped at 120 fps.

(Dunno if that's at all relevant information.)

Ah ok that looks a lot better. I'll still have to debug to make sure I didn't accidentally hook the wrong function. But the super low timings are likely from being in menu/etc since it's not actually "frame delta" you're seeing there but rather time in-between my update calls. 

 

I'll remove the debug hopefully later today if I've got time.

can you make a function like random open anus anytime? like breathing

[yiffles]

Love this so far! Currently using it along with the previously mentioned "SexLab Gape Morph SE" and I really enjoy the extra little bit of life this brings to the PC  ;3

At first, I didn't understand what this does differently. For anyone unsure: SexLab Gape Morph will generally just apply a flat morph to characters' anus post-anal (optionally enabled on NPCs too) that closes-up after some configured time, whilst this mod will apply gape to either (or both) of the utilized holes and also apply a slightly twitchy/pulsing/squeezing-hole animation (seen in the video in post #1) via quick morph adjustments. So far, both mods appear to mostly get along, with just a teeny bit of distortion when both are gaping my poor PC's hole beyond healthy limits. c: Being able to dial-in the settings in the JSON file in this mod and reload it on the fly really helps. Quicker than going into an MCM menu again and again, anyway!

Looking forward to future updates and more!

This could possibly, effectively be achieved by tweaking values in the JSON file (namely "DecayWaitTime") to where the twitching/"breathing" animation continues effectively indefinitely by picking a very, very long decay.

Assuming it could accept any double value (hinted by the default "4.0"), theoretically the max value you can configure is either the max value for a double (2e53 or 9007199254740992.00 seconds) or the highest value within whatever bounds-checking might be in the math that loads these settings. I tried -1.0 to see if that would cause negative decay, for funsies, but the gaping decayed pretty quick - so, the absolute-value (or default value) might be used, and it is just a counter. c:  Anyway, I entered 9007199254740992.00 for that value and for the brief amount of time that I watched it, I didn't see any signs of it slowing down anytime soon - whatever it caps at.

If you mean for it to start and stop randomly on its own, then that would require something else to kick it off (besides the obvious). With the right tweaks to the math for the sinusoid and an effectively indefinite decay time, you could probably achieve a more random, "breathing" sine wave that happens all the time and has some amount of randomness in its pattern with tweaks to the "JitterAmp" and "JitterFreq" settings.

i will try, thank you

actually i need anus open in random time but not break basic function of this mod: gaping after sex

You're welcome! 🫡
In that case, perhaps the author can add support for more than one concurrent gape function - applying the combination of the normal sine and the new always-running "breathing" sine to the character on each tick. 
Or, I suppose it could be made into a small standalone mod, separate from this. 🤔 It would need only the logic for the gaping animation and the loading of its properties from a config file - stripped of the penetration detection logic or hooks thereof - such that all it does is constantly apply its own sine. My question, then, would be: could Gaping After Sex + Gaping Always coexist, or would they be fighting over the bodymorph values - causing a VERY twitchy hole - or otherwise cause a noticeable performance hit? Gaping After Sex seems to work fine in my setup alongside SexLab Gape Morph SE, so it might be possible. (Although, SexLab Gape Morph just sets the hole to a flat value rather than a constantly-adjusting value (I think?). Things might go very differently with two mods frequently-updating the same bodymorph so much.) 

EDIT: In either case, if you can find some values for the sine wave that give the breathing effect (with desired jitter) that you like - and the author is open to the idea of implementing something - that would probably be helpful to them. c:

Very good idea. Maybe also have the NPC or followers gape for several minutes after equiping and unequiping a butt plug or the beads from Giant Anal Beads mod too. And maybe a gape spell too LMAO.

[hsztx]

Can you tell me what basic prerequisites are needed and how to install it properly? I used MO2 to install the compressed file and refreshed the animations, but there was no change in the game. Or is this mod simply ineffective for creatures?

非常好主意。也可以让NPC或追随者在装备和卸下肛塞或巨型肛珠模组里的珠子后，目瞪口呆地看几分钟。也许还要加个口间法术，哈哈。

I don't know what happened. I installed this mod using MO2, but the game hasn't changed at all.

[maverick53]

So far it sounds like a good mod with the potential of becoming a Great Mod.  Like many other,s I always play as a Male PC,.  If you extend the Mods capabilities to include Female NPCs,  I believe you will have a Great Mod. 

In the meantime, I will track your mod-site for any updates.

Good Luck!
