Personally I'd like the keyholder/caged thing for breaking new slaves but then once they've accepted their place and become someone's lover (often the keyholder, I've found) then it would be cool to just take the cage off and have the keyholder relationship end.  I think of it as a tool for breaking, not a forever thing.

Time to vibe-code your own version!!!  Might take like 30 tries though...

What a great mod, lesbian vampires have been eating so well since strapons were invented!

 

I'd like to point out some issues that you may consider patching in the future:

 

Denial - When a pawn is denied by their dom, it prevents their sex need from being filled, but everything they do with their dom still counts as sex act(orgasm), and their denial hediff is reset every time it happens.

 

Denial(but it gets worse) - when a pawn is being denied, their sex meter can't be filled (as mentioned above), causing them to try to masturbate all the time. There's a workaround, setting masturbation as available only in bed, limiting the time they waste trying, but now during daytime, they'll walk around the colony, doing quickies with anyone willing all day round, and as funny as it is, this ruins any productivity your colony may have. I'd rather disable denial for that one kinky pair that disable quickies for the entire colony, so as it is now, I consider denial broken and unusable when used together with sexperience. I'm not sure what a fix for this would be. Either putting a limit on the denied pawn, 1 qucike or 1 masturbation attempt per day, or alternatively, allowing their sex need meter to be filled while preventing the denial hediff from resetting.

 

Last thing is more of a suggestion than a bug fix, and we're not going far away from the denial. It'd be nice for pawns to be able to have keyholder relationships without the ideology being involved. Just a small chance that a submissive pawn and a dominant pawn decide to form a bond, without necessarily even being in a relationship, and with a possibility for the player to influence their decision if they wish so. Making it a part of the ideology is turning it into a big deal, this is what our colony is all about and almost everyone should participate, while keeping it private is better for flavor, when you don't want your entire colony to revolve around dynamics stuff.

 

Once again, this is a very cool mod and thank you for making it!

so... I've been trying for days to find the mod that's the culprit for having my femboy, futa and trans pawns have wonky heads, and I just found out that RJW Dynamics isn't compatible with Facial Animations. Every time I give them genes, or change their head to something normal, they instead change their head to something from a Biotech Facial Animations mod, like Alpha Genes.

 

a link to all the examples

 

 

I have the same issue. Is there a way to prevent head-swapping in the mod?

I guess for now, the only way to make this mod work for femboy, trans, and futa pawns, until the mod author returns and addresses this issue, is to not have facial animations installed.

 

idk about you, but I've decided to install other mods that add femboys and trans characters instead of waiting for this mod to update. Facial Animations is too valuable of an aesthetic mod for me to choose RJW Dynamics over that.

bro,I love this mod and I tired to use "Universal Apparel Tweaker" to move the rendering position of "tiny cage", trying to use it on other races,but it looks like it doesn't work at all,the cage just stuck on the pawn's chest.How can I solve that problem?

[XZIZ]

This is one of the greatest RJW submod i've ever used, it really changed everything in my game, i absolutely love the penis shrinking with flat cages and i love the strapons even though they have some issues like some times they appear as normal penises instead of a strapon.

 

I'm also having issues with giving quirks to submissive pawns, when i order the training for a quirk, only the dominant pawn gets it, and I would have loved for schedualed releases to be fixed, right now I'm having issues with it.

 

The most i can do to help is by reporting bugs, make suggestions and donate, I would love if there was a way to donate to you ProbablyInert.

 

Thank you so much.

I really like what this mod wants to be, and how far it's gotten there. There are a few issues, however. I will note that I have been testing the game using the dev mode and the Character UI mod, and I've looked a bit through the .xml files, but not the .dll one. I'll try to list the issues in order of higher importance and relevance:

 

The soft D/S system has bugs and/or design inconsistencies

 

Submission seems to be ruled by a hidden health condition called "Submission". When it's properly working, its intensity is shown at the Dynamics tab, provided you're capable of seeing that tab. When a pawn gets put in chastity and gets a keyholder, submission gets set to 60%.

 

Now, according to my tests, it would seem like the soft D/S system would work through this condition alone, except there's an issue: if the Submission condition doesn't exist to begin with, it isn't created after D/S contests. If you manually give your pawns the Submission condition and set it at a very low value, it will be able to grow naturally, and thus the soft D/S system will work properly.

 

The other issue here is that, looking at all health conditions, this condition isn't actually how the D/S system should work. Instead, it seems to me that it should be ruled by the conditions "Dominant Streak" and "Yielding Streak", as it would be more coherent with both the descriptions of the mod overview, the settings menu, and the conditions' themselves. However, these conditions don't seem to spawn naturally at all.

 

On this matter, I should also mention that I haven't seen any data in the game that points to the idea that any two given pawns are developing a soft D/S relationship (as an independent value beyond a given pawn's personal traits and conditions), even when I cheat the Submission condition for them. If this is an attribute that should exist in the game, I suggest adding it to pawns' "Dynamic" tab, so that we can properly see what's going on with it.

 

The sexual dynamics meme and its related precepts have wrong requirements

 

The Sexual Dynamics requires one of these precepts: ["Men rule", "Women rule", "Futas rule" or "Femboys rule"]. The issue is that it locks you out of the precept "The dominant rule", and the precept "The dominant rule" ALSO requires you to have the Sexual Dynamics precept, which means that you can't use the "The dominant rule" precept at all, unless you use the dev mode to cheat it in. There are several similar issues with the Ideology code in general.

 

I have the (unsubstantiated) impression that these requirements were set so that the game wouldn't organically create NPC ideologies with these precepts out of nowhere, but there are sensible methods to achieve this outcome. It's been a long while since I last modded Rimworld so I can't remember with much detail, but I suggest taking a look at Rimworld's vanilla Defs for Ideology.

In general, making the new precepts NOT require Sexual Dynamics would be best to give the player extra freedom. Making Sexual Dynamics require all four of the new rituals seems overkill to me.

 

Bugs regarding chastity keys and relationship status

 

I've noticed that there's a special interaction where, if pawns A and B are lovers, and pawn C is the keyholder of pawn B, pawn A will go to pawn C and demand pawn B's chastity key, to which pawn C always seems to agree to. I have some opinions about this (should it be configurable, should it depend on dominance, etc.), but right now the main issue is that this interaction doesn't remove pawns C and B keyholding relationship, but rather adds a new extra keyholding relationship between pawns A and B. Beyond the inconsistency, this generates new bugs afterwards, since Pawn B has multiple keyholders even though it shouldn't be possible.

 

-------------------------------------------------------

 

I think these are the most glaring problems so far. I have a few other comments, but either they're minor or it could be argued that they aren't the domain of this mod.

 

Chastity cages block a pawn's pussy

 

The way chastity devices work, they block all sexual interactions with a pawn's body parts in the Genitals section. This means that, even though chastity cages fulfill their intended function of locking a pawn's penis, when that pawn is a futanari, they also block their pussy. I'm sure everyone here will agree that this is horrendous and a crime against everything that is hot and sexy. I believe this is an issue originating from RimJobWorld itself, though it could also come from RJW Extension's code. I'm only bothering to bring this up because I like this mod's end vision so much that it's only now that it's become a problem for me 🙃

 

This mod's chastity devices and RJW Extension's chastity devices have different functionality

 

I haven't run extensive tests, but it seems to me that some of this mod's functions don't work correctly when the involved chastity items come from RJW Extension (for example, chastised pawns aren't properly unlocked when it should be their time for it). I'd suggest adding patches that add the missing information/labels/attributes to RJW Extension's items, which should be possible to do without making RJW Extension a hard dependency.

 

Suggestion: Pawns' D/S calculation should be explained in the Dynamics tab

 

As far as I've seen, a pawn's D/S position on the scale depends on: their dick size, their traits (including Abrasive, Masochist, Tough, etc., but generally only a small portion of all existing traits) and some health conditions such as submission. Then, whether this lands them on Dominant, Switch of Submissive depends on your settings. This is, assuming there aren't any special conditions that locks them in any such position to begin with (being a keyholder locks a Pawn as a Dominant, for example).

 

Adding a tooltip that shows where a pawn's natural dominance comes from would be great to guide players.

 

Suggestion: A slider in settings to give extra base dominance to cis female pawns

 

Given that the most important factor to evaluate a pawn's dominance is dick size, women without dicks are almost always bottoms or possibly switches, unless they're locked in a Dominant position due to your ideology precepts. This removes some dynamism from a playthrough where you're playing without any gender supremacism precepts, since women will very rarely be naturally dominant.

 

This could be fixed if we had a customizable slider to give cis female pawns some extra base dominance, whether it'd be 0 (at which case they'd still lean bottom), equal with average-sized dicks, or the same as gigantic dicks.

 

Suggestion: A keyholder should be able to start sex interactions involving their chastited subs' locked parts

 

This would require adding a patch that replaces some function/s from either base RJW or RJW Extension. It might be disabled by default, but possible to turn it off it a sub's Dynamic tab if they're locked in chastity. This way, a female pawn locked in a chastity belt would be possibly bred *only* by her keyholder, and a pawn with a dick would be able to get it wet *only* if their keyholder wants to get fucked. This would have great consonance with the settings that select sex interactions depending on the dom's quirks.

 

 

 

I have more suggestions, but these are probably the easiest ones to implement and the ones which I believe should be more "obvious". I really hope you come back soon, @ProbablyInert, this mod has amazing potential.

Does anyone know how to end a keyholder relationship?  One of my subs has fallen in love with her keyholder and they are getting married soon.  When I take the belt off her (so they can make babies) her original keyholder takes over and starts making her obey and stuff.  That's a citizen's future wife dude!  This guy isn't carrying the key (it's in the device nobody is wearing).  Having him put the device on her, pick up the key, and unlock the device doesn't clear the relationship.  

 

Not an ideal solution, but you can remove the relationship with her keyholder with the Character Editor mod: https://steamcommunity.com/sharedfiles/filedetails/?id=1874644848

Sooo should I ask again about adding an option to use Thin Body instead of Standard Female Body for Femboys? I never actually got a proper answer last time.

Has there been any news about the creator? Please, I hope they don't abandon this mod.

That is a good idea.

 

Actually I discovered that when you Dom goes to "tend" to the sub a "End Arrangement" button appears in the Dom's Dynam tab.  At least there is if the sub isn't wearing a belt at the time.  Creator is seriously amazing and thought of so many things. 

[Bingusasdf]

started keyholding relationship

ended keyholding relationship

doesnt seem like I have much control over who picks up the key unless i force equip it every time, and even when its force equipped its hit or miss as to whether that instantly starts and ends the keyholding relationship anyway, maybe im using this mod wrong. Also cages prevent vaginal for futas for some reason.

当安装了Big and Small - Framework后，伪娘的体型会被强制切换成标准男性体型——即使你通过角色编辑器或其他来源把他们调回去。我也不知道为什么，就是这样。我尝试过调整RJW Dynamic和B&S的设置，但据我所知，没有哪个设置能解决这个问题。本应修复体型的RJW动态保险机制确实有效，但它一直在与之抗争，根据我的经验，基本上根本不起作用，总是来回切换。我只启用了必须的模组，旁边还有罪魁祸首。

Currently, in version 1.1.3, if set correctly, after taking the trap pill and opening the character editor, you will see the behavior of forcibly identifying Trans as a female (similar to the Femboy Gene in RJW Genes), which will cause this pawn to forcibly adopt the female standard body.

 

I am also using the Big and Small Framework.

I would like to be able to enable pregnancy from a dildo in the settings.

[des]

Instead of completely removing the pregnancy option for strapon, can we get ultra/archotech level that can actually do so?

Low level strapon can stay as is.

I am also using the Big and Small Framework.

But here comes the problem.

In version 1.1.4, if the Femboy trait is added using the Character Editor, the gender will be set as Femboy (while maintaining male in the Character Editor), with a male head, NL male face (keeping the original components), and using the female standard body.

However, if the trap pill is used, it will change to the trans gender (becoming Female in the Character Editor), with a female head, NL female face (randomly refreshing the components), and using the female standard body. At the same time, the name of the pawn will also be changed.

 

------------------------------

Edit:

 

The reason for this situation is that the chest size of the male pawns I used for the experiment were 1%, only males with a chest size of 0% can transform into a Femboy, and changing from male to female in Character Editor will randomly generate NL facial components(And it will be renamed, which is equivalent to creating a new pawn.).

 

All the male pawns created by RJW have 1% of chest size. Therefore, the trap pill will only generate trans rather than femboy. 

 

Update:

 

During the DEV fast testing, male with 1% chest size successfully generated Femboy. It seems that this issue occurred in the old save files. However, changing pawns to "trans" or "futa" would reset the their full facial parts and renaming them are still be problems.

 

--------

At the same time, in this version of the mod, if the pawns' genes are altered (with Biotech DLC), the facial components of the [NL] Facial Animation will also be changed. Without this mod, modifying the genes will not adjust the facial components.

 

- This problem lies with normal male/female pawns that are not femboys. Only femboy pawns, after having their genes modified, will not have random facial components. And change femboy's facial components to the same components but in female version.

 

As I mentioned earlier, the Femboy trait will retain the NL male face (keeping the original components).  It is not until the genes are altered that the face will transform into the female version.

So... When I use this mod, and use the dynamic meme, it seems new born child of the colony is always femboy, and it also effect the animal, turns every animal of the colony into male, which really screws the farm system. Is it some mod conflicts or something?
can any one help me with this? this is my mod config file

I am going out of town and won't be able to work on this until August 2nd.

 

The mod is not abandoned and I have not lost interest. I would rather say I won't be around now than go silent for three weeks. I have posted version 1.1.3 and left 1.1.2 up as well in case 1.1.3 has a bad bug while I am gone.

 

Keep posting bugs. I won't be able to answer them, but I will read the whole thread when I get back and work through it. A report with your Player.log and your mod list is worth ten without. If RJW updates and something in here breaks, I won't be able to fix it before August. The source is MIT and lives at gitgud.io/ProbablyInert/rjw-dynamics, so patch around it if you need to, and post it here if you do.

 

Thank you all for the reports, testing, and ideas. See you in August.

At least saying SOMETHING would put at ease the doubts I've been having about this mod not being abandoned... I really wanna use it again, but I can't while it's incompatible with Facial Animations.

I turned off the "trap spawn" option in RimJobWorld, and then in RJW Dynamics, I increased the "femboy spawn chance" to 1%.

 

Then you can use the Femboy gene from RJW Genes to control offspring's trait.
