ha i asked the same thing

I will look at expanding support to other bodies down the road. Currently SFF is the closest one to having good support and functionality for managing the bodies morphs. I am currently working on a new framework for managing interactions and triggering animations for all mods (including this one).

SFF has alot of issues stm tho, but SFF and MWV do seem to be the only 2 actively updated bodies tho.

ok for some reason the sff setting in the notes wasn't working - clicked on vanilla then back to SFF and it works fine now!  all is good.

Hi - I'm super excited to see where this mod goes. 

 

I read comments that touched on some of the other mods I play with in other games (examples being fertility mode in Skyrim, family planning and wasteland dairy in FO4 and several others that were touched on) and I've been waiting for a mod like this to hit Starfield. I haven't experimented with it too hard yet because my current playthrough is my first playthrough and I, frankly, have no idea how to work Xenomasters yet! But I can't wait to see how this expands. I'd love to see named NPC support, this was mentioned in another comment, if you have a human child but I understand if that's complicated. I like the idea of bouncing between human and xeno children depending on who just gets to you first. 

 

All in all - great work on this so far and I'm excited to see where it goes!

Thank you for your support!

These are all things I have planned. I set this framework up to be extensible so it can easily incorporate and adapt these different features. I've had to detour to implement what I am currently naming SIF (Starfield Interaction Framework) so that animations can be dynamically loaded with SAF through behaviors, hotkeys, triggers/events, dialogue, etc. This will make it easier for other mod authors and animators to implement animations in their mods or any mods using tags and a json database. I also built a blender tool to make creating animations for SAF super simple. Join the discord to gain access to the documentation/guides and the plugin. The plugin essentially helps you import in models/skeletons, start animating, export into the format SAF needs, and update the skeleton dictionaries and the animation libraries for you.

I'll create a separate post for this once I'm done testing/implementing SIF ❤️

[Mimirue17]

I am just so happy that almost all the adult mods have updated recently to adapt SAF (which has an active modder behind it unlike NAF in any game) so we should be good long term.    With new mods like this, my hope is the adult community actually takes this game seriously as an option to create content in (so many gave up and moved to FO4 or back to Skyrim)

 

[Mimirue17]

I put it in discord, but might be a good idea to add a footnote on the main page, if the pregnancy sliders do not seem to function there are 2 things to try.   1 just toggle the settings back and forth (vanilla then back to SFF) and if that fails reinstall this mod and change the setting again.    I seems, at least in MO2 that mods are conflicting but are not showing the conflicts like in Skyrim or FO4.   Not sure if its just different file structures or something that MO2 is not recognizing as doing so.   From what I can tell, in cases like this the last mod installed wins, regardless of where it is in the load order.   Which would explain some of the issues I have had in the past with mods.

I could look at setting up a discord server if that's something that people would be interested in.

 

 

My intention is that it won't be specific to just SFF Bodies and that you could use the mod completely without any of the xeno/parasite stuff. Since the next thing I'm working on is an interface to control some of the settings for Fertility Framework, some of that could start to be in the next release. That's why I wanted to upload the mod on here and see how much support/feedback I could get. I have a fulltime job so I want to be sure a mod/framework like this is even wanted before I dump more time into it.

 

I essentially started this mod for myself, but while also keeping in mind that it could be built out to incorporate a lot of the elements of 'Fertility Mode', 'Milk Mod Economy', 'Family Planning', and 'Wasteland Offspring'.

Id say "Family" (and fertility) mods have quite a few people interested in them (whether that is the NSFW side or SFW side of creating a family in starfield). Ive seen lots mention how they would love to be able to have a family in starfield. 

Additionally I asked a few people I know who play Starfield if they would install a mod that allows you to create a family and their answers summed up to "yes".

Does this work for human on human? (Like M and F?) or is it only Xeno?

[mystic_cat]

It will work for human on human and human on xeno. I'm currently working on the next large release that removes the xeno master dependency. I've built in a follower and offspring system for actually having a family and what not. 

I've been working with the mod author for SAF, so I can finish building SIF for handling all of the animations, and then I can release the Fertility Framework update and Starfield Interaction Framework.

That seems dope.

I have a question about Xenos in that update. Would there a way to avoid / disable the Xeno "Interactions" that happen when they are near you and you sleep? (Like in that Note Item that is for settings or in the gameplay options setting?).

Yes! I've been expanding the settings and controls so certain features can be disabled or modified.

Love this mod, but does it work along with Star Wars Genesis mod pack?

I would have to do some testing to make sure there are no conflicts. I'm not familiar with that mod.

It's a massive mod pack, turning the game into Star wars theme, it would be awesome to be able to play with this mod

btw I noticed that Breast pump is not available to craft yet, so there is no way to get it now?

I'm confused does this mod not use custom animations? I don't see SAF as a requirement

It will. The current release doesn't have it as a requirement because there aren't animations. My next release has a lot of changes to Fertility Framework, including SAF support, SIF Support (animation framework), and an animation pack for some animations to start with. I didn't get to finish the release before I went on vacation (I just returned). Then I saw ANOTHER update just came out for Starfield yesterday.

What is SIF? I thought SAF was the latest animation framework for starfield, is that a new one?

SIF is what I'm building to compliment SAF. Something that can "direct" the scenes and interactions. That way other mods can share animations with tags and whatnot.

That sounds awesome, I actually just built a mod for myself recently similar to those fallout and skyrim mods where you have a libido meter that goes higher the longer you go without any sexual interactions, creating debuffs, and having sex lowers it.

Right now it just uses 3 masturbation animations and a hotkey to trigger them, and I was thinking if it was possible to somehow make it so that sexual interactions from other mods (snu, ebanex) also lowers it, but no idea how to do this.

A mod that makes mods use animations from other mods (assuming it can also play its sound files because generating sound files through wwise is horrible) sounds exactly like what we need.
