Mod Unity [Secret Flasher Manaka] Cosplay Loader Mod 2.2.1

[Schmel143]

View attachment 5334384

Overview:
This mod loads custom cosplay parts and injects them into the game.
This is currently just a replacer but I'm looking into modding in custom categories and equips.
You can now create completely new parts without affecting base-game parts!
I've included all of the cosplays imported before 10/16/2025 in the Mega link with some tweaks to the categories and names. Currently 24 parts are available!​

Modder: me
Mod Version: 2.2.0
Game Version: 1.1.1
Language: English

Known Issues:
- Your game will bug out on load if you remove this mod and have any custom parts equipped or try to load a registered set that contains a part. KEEP A BACKUP OF YOUR SAVE JUST IN CASE
- Bone deformation on butt, crotch, and upper thighs is a bit janky and clips
- Elbow bone deformation is completely fucked - looking into it
- The halloween outfit clips with the nipples. The cosplay I imported didn't have nipple sliders built in.
- Certain equips have multiple meshes that don't properly disappear, like the Guard's whip.
- Sliders are a bit janky on certain equip pieces

wow this mod is really cool, can you also make custom hair and eyes or maybe even custom poses?

Thank you! Now that I’ve got custom bones and dynamic bones working, most of the hard work to add custom hair is done. It’s on my list for future features.
Not sure how eyes work in-game but I can add it to the list of features. I imagine it’s just additional textures/materials.

It's great to see all this work getting done on your end, Tetora... Meanwhile, I'm still chasing after deserializing the assets file like a madman. It feels like I'm inching closer and closer to it, but I've mostly just been learning about how such a file can be made, and not really how to write it into a workable format. I hope I'll have something to report on getting the main assets of the game into working "master" files, if it's even possible to reverse engineer this hard lol. Maybe in a few months or so if I keep at this lmao

What I can tell you now is that the assets file that's in StreamingAssets is definitely the asset files serialized in binary. However, I have no clue how to, or if I even can, write these files to workable "master" files. I'm slowly getting closer to at least finding out when in runtime these files get read and deserialized by the game engine, maybe, but my experience, knowledge, and coding aren't up to the task of actually utilizing this new knowledge, even if I attain it. In short, I'm fighting a losing battle on my own end. Sheable is my eternal foe, if I ever manage to crack this asset file open, I'm going to spam tweet his barely active twitter account and shove it in his face lol

Good luck with this endeavor that actually has some fruits to show, I just wanted to let you know that my efforts are indeed hopeless, in case you might've been curious

Sorry to hear it’s been a pain! I tried accessing the meshes in memory at one point but couldn’t get all of the data. Wrote an exporter to dump Mesh data from memory but it lacked any of the skinning stuff I needed since the API had the Mesh objects set to unreadable. I think you’re on the right track trying to dig into the asset files but once you have those I’d imagine the best next step would be to make changes and inject the modified versions back into the game at runtime instead of trying to patch it directly. I dunno, but I hope you have some success.

One thing I’m still trying to figure out is the cleanest way to modify enums. I can inject stuff into objects and classes at runtime but no clue yet how to change enums - this is a hurdle for custom categories, custom scenes/areas, and other systems in game.

Here's a skirt I did with the new update. I kept the config identical to the rabbit ears ones TetoraFetora did. I'll keep messing with this one.

 

[TetoraFetora]

Hello hello~ I've posted an update for 2.2.1
This is a small bugfix update that prevents the game from locking up if you save your game with a modded part equipped and then delete that modded part from your ModCosplays folder. This will smoothly scan your equipped cosplay parts and snip out any broken entries. As always, back up your saves!

I think there may still be issues with saved sets so I'll probably need to release another patch for that.

TetoraFetora Could i request more body piercings in areas like the navel, nipples, and intimate regions? I searched around but didn't find models for SELESTIA.

Also, is there a way to design pixelated clothing that works as a kind of visual censorship?

I haven’t seen many Selestia piercing parts but I’ll look around sometime. As for the pixelation - yeah probably. If you were to look at the mosaic material in game with Unity Explorer you could create a ModMaterial matching it and apply it to modded clothing. Probably. I haven’t tried, but I did try applying the fur material to the body mesh with comical success.

There are two nipple piercings from the base game and two piercings from cosplay mod (barbell and navel). It would be nice if we could see more in the intimate regions.

have anyone tried to convert Koikatu's mod into SFM mod yet?
cause it already have a huge among of mods,
if it works we can make SFM much more joyful with tons of mods

 

[Muhdog]

So, apart from me being dumb with Blender, this is actually quite easy to do.

I've always felt this game lacked a regular bikini for a more natural exhibitionism progression.

Okay, just as I was about to post this, I realized volt2323 had already converted this bikini. But since I've ported the ribbons and strap, I'm posting it anyway.

I like your line of thinking but I have no idea how I’d convert Koikatsu clothing to be compatible with the Selestia’s skeleton and proportions without massive clipping.

On a side note, I love the idea of sharing cosplay outfits and sets via card images like Koikatsu has. Then we could have a booru to keep everything in one place.

Nice, glad you were able to port the piece with ribbons and straps. I’ve still gotta update the documentation
