Gardening
-Sims will no longer autonomously research a plant during drinking situations, strip poker or during sexy picture time. To me, it didn't seem like the right time to do that. (honestly, sometimes getting the sims to do something is like herding cats.) **Update, Since just by having plants seems to make sims "Research Plants" such an incredibly high priority I've decided to remove the autonomy for sims that have the Sexually Awkward and Pervert traits.

 

 

I'm having an issue where the research option is just never available on plants when it should be and this mod is installed. I have replicated the issue with only this mod installed, if the mod folder is empty I get the research button, if I add this with or without the dependencies the research button is gone. 

 

Is it possible that along the way something has become broken with the above change you made to gardening autonomy in 3.1.0?

Interesting! I may have, when trying to stop the autonomous "research plant" taken out the entire interaction. (the autonomy on it is obnoxious. you could be making out in bed and then suddenly outside "researching a plant" ha ha.) But thank you for this. I know I didn't spend much time on it when I did it so I will have a look at all that and figure it out. 

EDIT: Yes, I intentionally made it so sims with either the Pervert or Sexually Awkward trait can not research plants. (this really should just be on an addon and that way people can install it or not maybe.

Ah ok that makes sense. It's such a tiny little thing and it's contextual too in that it only shows up when a plant is blossoming so I get how it could be easy to overlook. 
This character is a pretty normal one where I'm not doing any perverted stuff so I'll just take the traits off them, that way I can keep the mod in for my other sims. 

Thanks for the quick reply!

It is. I changed it back that day because you were right. 

Unfortunately, it isn't working anymore. I have 4.2 from Patreon, and my sim has hard nipples turned off (visual overlay applying over clothes), but during sex, they don't appear like they used to when engaging in her favourite sexual category. The "Hard Nipples Exposed" moodlet doesn't show up anymore then either. It only works when I turn the visual appearance hard nipple overlay on. But then it is just constantly showing over clothes, which is not how it used to work before.

 

It seems all the boob buffs are just gone by default when you turn hard nipples off. There aren't separate controls for it, or at least the separate controls don't really seem to be working. Cause when I turn hard nipples off and leave boob buffs on, it doesn't make a difference, the buffs are gone along with the visual overlay. When I turn hard nipples on, eveything comes back, buffs and visuals. Same for male sims, the boner buffs are all gone too when you turn off the visual appearance of bulging pants off. That's a shame cause the buffs are one of the most fun features of this mod. I'll revert back to an earlier version for now, but I hope it can be fixed eventually. Thanks Skarrd!

Hey - How does the normal trait work? Does Seduction work on sim's with the normal trait? Wondering how the days after function works with normal sims.

[Noir6137]

Have you thought about giving women erections? A swelling of the labia and clitoris? Since they obviously get them, and having just the nipples react is kind of generic. Also, since we know there is a sex preference for 'vaginal,' it could add a bonus when they have these erections—like a stronger excitement or something, I don't know, it just crossed my mind

Do you mean the custom drinks? Or just can't make drinks at the bar at all? There are teen restrictions if it's the latter. If it's the custom drinks, they were changed and turned in to unique drinks now so they no longer conflict with other drink mods or base game drinks.

And this is after changing the two controls for nipples correctly? There's an on/off switch in game play. (you would want that on) That would be the buffs. And there is the visual switch. Found in the visual section. (you want that off) 

 

With visual off and game play on the nipples should still show during preferred sex. 

 

And that's how it's set for you but it's not working? Have I got that correct?

The normal trait comes with basic functions like, being able to get hard nipples/pants bulges. They are able to drink alcohol and receive the drunk effects. They can play strip poker. They lose the attitude buffs that come with the sexually awkward and pervert extremes. The day afters have been applied and do function with normals. (day afters should work with all sims with or without one of the main PEP traits.)

I am a fan of all the involuntary physical reactions that have been added so far and I love the idea. I will add it to the list for sure. This may require a modeller and in that case, I may need help with that, but I have been constantly learning and may get there myself)

@skarrd My sims cannot serve the unique drinks that come with your mod at home. They can be served the drinks at a bar but not at home. All of them are YA and older.

Yes! They absolutely are. The alcohol comes with restrictions for teens. Teens need permission from adults to drink through interactions or there are cheat rewards the player can purchase in the trait rewards section. The first post in this thread has a massive amount of information about the alcohol rules under Alcohol->Teen Restrictions   for more information.

Looking forward to full-on "darker" non-consent interactions being added. You'll be earning yourself a new Patreon sub when that day comes.

New Features released on Patreon:  (expected release date June 2-5)

 

Ver 4.3.0

New Additions
As the new underwear/undressing/clothing destruction system continues to develop, the next logical step was: 
 Autonomous Dressing/Undressing. (needs to be turned on by player)
These types of autonomous behaviours will need to be turned on in the Perverted Expansion Pack Options for players who want to experiment with the new autonomy one sim at a time. I also added the trait to the WW attribute menu for players who just want to jump right in to test this out and add the trait to all sims.
Sims (teen-elder) will begin to autonomously undress at logical times now.

So far:
-A male sim that gets the tight bulge buff, if alone, may remove his bottoms. But will dress up if someone comes over. (that is not in a relationship with, so they won't take their pants off if family is around)
-A sim male/female that gets the wet clothes buff, if alone, may remove their top. But will dress up if someone comes over. (that is not in a relationship with, so they won't take their top off if family is around)
-Sims that become "sexually flustered" or "sexually frustrated" or "lost inhibitions" will begin undressing voluntarily. (top or bottom or outfit) when not in a haunted house. (there are too many dangers to the sims clothing in the haunted house already.)
-Pervert sims that become simply horny, may possibly voluntarily undress. (top or bottom or outfit)
I've added the autonomous dressing up interactions to the system. Sober, sexually awkward sims will now dress up automatically, (as long as they have clothes to dress up with, not being coerced or meeting the conditions above) when a sim who they are not in a romantic relationship with sees them undressed.

-If children sim can see, sims will dress up automatically.

-Sims that have had their clothing destroyed in some way will not be able to dress up. Only sims that have removed their clothing will.

For players that have the "Seasons" pack there are additional autonomous opportunities below!!
Seasons
-A sim (male or female)that gets the "sweltering" or "overheating" buff when inside a residential home (from thermostat turned to warm on a hot summer day) the sim may autonomously strip to attempt to cool down. (and it does)
-A sim that gets the "sweltering" or "overheating" buff when outside in public from wearing too much clothing on hot summer days:
⦁     If male the sim may autonomously strip shirt and undershirt to attempt to cool down. (and it does)
⦁    if female and a pervert, may autonomously strip shirt (but not bra, unless the sim has the No Bra Preference) to attempt to cool down. (and it does)
These New autonomous undressing interactions makes the classic juvenile ploy to "crank the heat" in the house to get a sim to strip possible! (make sure not to kill anyone okay!)
Spa Day 
New interaction for Pervert- "If you take your bra off I can give you a better massage." becomes available if there is a massage table on the premises, the pervert has already gotten the targets shirt off using the interaction, "If you take your top off I can give you a massage." Results in a high chance the target removes bra and then asks for a massage.
Now when asked: "If you take your top off I can give you a massage." and the target is a man, the man will also take his undershirt off automatically if he is wearing one.
***Creator Note about the undressing/dressing autonomy: This is what I was trying to achieve using WW undressing system for so long. (and failed) This, along with the new underwear system is very cool.

 

Environmental Awareness (AKA proximity buffs)
Continued the system changes/bug fixes etc. Too many to list. Some has gone better than expected. Some stuff is being stubborn.

 

"Day After" Dating
Introducing a collection of "Great Sex" interactions that will only become available the day after if one of the sims involved has learned some sexy secrets about the other sim. (for more information see Social Dynamics->Sex Buffs)
New Interaction for Pervert: "You had me SO turned on." Becomes available after 2 drunk sims that are not in a relationship with each other (girlfriend/boyfriend,  married, engaged or promised) have teasing sex (and not hand job, oral, vaginal or anal) and the sim target: Knows your sims "Sensitive Areas" secret (or "putty in my hands"). resulting in custom buffs for each sim (from their perspective) and relationship markers to remember the event and a custom notice informing the player of exactly went down. (Plus a medium romance relationship bonus)
New Interaction for Pervert: "You had me SO turned on." Becomes available after 2 drunk sims that are not in a relationship with each other (girlfriend/boyfriend,  married, engaged or promised) but Player sim is in a relationship, and has teasing sex (and not hand job, oral, vaginal or anal) and the sim target: Knows player sims "Sensitive Areas" secret(or "putty in my hands"). resulting in custom buffs for each sim (from their perspective) and relationship markers to remember the event and a custom notice informing the player of exactly went down.

Changes:
Changed "What happened between us was so hot."-> "I had a great time with you." (to make room for the new Great Sex interactions.)

 

Perverted Expansion Pack Options 
-Underwear Preference Controls: By default, sims will start with colour match preferred. 
-Underwear Preference Controls: Colour Match no longer requires Top and  Bottom colour preferences to be both set to "pastels" or "darks" to appear and if a sim has no colour choices set but has colour match preference the sim will choose a matching set from all available inventory. (either dark or pastel)
-Added New Autonomous Dress/Undress On/Off in Game Style Options. (**See Autonomous Dressing above for more info)

 

Automatic Underwear System

 With each update this system has improved dramatically. This months update feels like it's starting to meet bare minimal requirements to run properly. This is quickly becoming one of the coolest features in the mod. 

 WW Prep: -The Alter Outfit menu is now available to sims during WW sex. (To be available, WW settings must be set to Vanilla Interactions available during sex.)

By default, sims have access and will wear all available underwear. Colour Match is on by default. 

 

How Player choices effect underwear that will appear for a sim:

The player picks the sims preferred underwear categories. Once a choice has been made, the sim will only wear from the category chosen. The sim can add as many underwear preference categories as they wish.

 

The sim automatically picks the items. 

The player doesn't know what they're wearing until the sims outfit is removed. Keeps a bit of mystery between the player and the sim.

 

This Months New Underwear Deliveries (straight to your sims underwear drawer) to add to previous inventory.

(If you would like to see all inventory, go to the first post in this thread and go to "Latest Additions")

Bras

Balconnet

 

Demi

 

Full Cup

 

Push-Up

 

Panties

Bikini

 

Brief

 

Classic

 

High-Cut

 

Thong

 

Men

Boxers

 

Bug/Error Fixes
-Added the missing condition that was informing the player that a sim had no panties on, when in fact, they did.
-Found and added the missing conditions that were preventing Sims who had obtained "Putty in my hands" or "Knows each others (insert any sexy secret here)" from receiving the proper sex bonuses.

Thanks for making it!

[thornyrosedd]

Hi Skardd, thanks for your work. Is there any plans to integrate this with wicked whims no underwear trait. I notice of irrespective of whether a sim has the no underwear trait selected in wicked whims if they have set to no underwear in your settings preferences underwear will seem to materialise (typically the bra) almost as if it only works for one underwear slot. Is there any plans to resolve this or allow for some sims who do not wear underwear (or don't wear bottoms or bras)? It really breaks the immersion or looks really odd depending on certain characters outfits or traits and seems quite buggy which has put me off using some features even though I really like them. Not sure if it's a compatibility or settings issue I can troubleshoot or just a bug with this mod.

Hey! There are separate controls for no bra preferences in the Perverted Expansion Pack as well? It's not that is it? But if not, I will look in to this. You are the first to report it and I have not seen this myself. Is this when clothes get destroyed in some way? Or is this when undressing using WW undressing system? Because if it is the WW system, there might be something else going on here maybe.

Hi, it happens if I set my sim to have no panties and bra in PEP but when I rip their clothes off or if they woohoo the panties and bra (most often the bra) respawn whether I have sim set with the no underwear trait in wicked whims or not.

This is just a hunch but I wanted to throw it out there. With the PEP's new underwear system, it had to run completely independently of WW's undressing system. So the player needs to make sure they stick with one system. 

If any clothing removal/destruction happened before the sex, you must continue to use the PEP's "Alter Outfit". If in the middle of an outfits removal the player uses WW's "Outfit" and any of the clothing removal options from there, it will remove all of the PEP's clothes removal/destruction buffs and resets. This is my best guess off the top to explain re spawning underwear. I am still making adjustments as to "what is required" to reset in an attempt minimize the incompatibility of the two systems but sticking to one system should fix that. This is definitely something I'll need to spell out in the instructions.

 

EDIT: And... there is one more thing. Some animations have automatic outfit change instructions that come with the animation. Take notice if it's the same animation where the underwear re spawns. 

 

Regardless of that I will look in to this and add if I find anything.

All I ever read is:

 

"You turn me on so much"
"You make me so horny"
"I'm so aroused," etc.

 

When I'm horny, you grab a girl and head into the next room to have some fun!

 

But does anything ever actually happen autonomously at some point? Instead of just standing around like an idiot and spouting the same old drivel over and over?

 

And what about interactions that can't be carried out because the necessary objects haven't been placed (e.g., a bush, a closet)? Up until now, it’s always been a glaring flaw that the game would prompt you to perform these actions even when the objects weren't actually there!

 

And why ask for permission in the first place? If you’re a pervert, you just drag the girl into the bushes—end of story.

 

These are the kinds of things that have stopped me from continuing to play with your mod in the past.

thank you for replying so quickly with a solution. I'm going to redownload and I'll stick to your system and see how it plays out. I'll update you if I run into any more problems.
