Amazing, I love this soo much! I am curious, it seems like you are going to make this work with her playable form. However depending on how SEGA does the playable characters (which I have a sinking feeling, not the way I would like. *cough* not being able to do every island/cyberspace etc. *cough*) would you be willing to make a version this replace Sonic also? (Could use the Amy frontiers mod also for her animations.)

It's a maybe on whether I would make a "Nude Edition" for Amy Frontiers.

Ok so, playable nude amy can be a reality

[Catnatic]

Playable Amy in Another Story is now nude! I made a couple edits to the model by adding a navel and colouring in her inner pussy. There's no variations for now.

 

 

You can find the latest version of this mod here:

 

Old Version:

Spoiler

Download:

amyP.pac

 

HedgeModManager isn't working at the time I'm writing this so you have to replace the original .pac file with the modded .pac file in:

"SonicFrontiers\image\x64\raw\character"

You can also do the same for NPC Amy (amy.pac, NOT amy_orig.pac) with the previous version of my mod.

 

Next time I'm releasing an update for the mod, it's gonna be something I would consider a proper 1.0 release (that will follow the HedgeModManager format again).

Ideally, I would make two versions of the mod: one with story-friendly cyber ghost shader and one without, but I'm likely going to do the latter first since it's almost already done and easier to do. I'd be also looking into the "amy_orig" (non-cyber-ghost version) and "amy_birthday" (update 2 costume) models to make the mod fully complete, and try getting that fur shader to work properly on her entire body.

And its completed, amy nude mod is now available, created by Shawn Guku who also made the nude mods in the SA2 game, hope you guys enjoy.

 

For Details, in the real world she has her dress on and she's got nothing on underneath, and in the digital world sadly her dress did not survive the conversion process. Silly ancient computers.

The Void willow/GMP shantea/Amy head hack model was used to make this while keeping the original hands, head and feet from the game.

Does Shawn intend to make this mod compatible with playable Amy?

ow i wanted the other body model

that's what's i was thinking

[Catnatic]

Remember when I try to apply the fur shader on Amy's entire nude body and it doesn't look right because it has black splotches on her back?

Since then, I've been learning how to use HedgeEdit to replicate how the base game used materials. Turns out there has been documentation of it on the open web.

So what I did was basically copy the original fur material and have it use my own textures instead of the game's base textures. And by my own textures, I mean this includes variants like normal map (nrm), falloff (fal), flow map (flw), and parameter (prm: specular, smoothness, roughness, and ambient occlusion).

I'm still learning on how to make these texture maps aside from normal (thanks Nvidia Texture Tools Exporter) so I just set the material to use the abd (diffuse/original) version of my texture for the time being and... it doesn't look too bad.

 

In other words, Amy's furry back appears to be fixed which is great.

But not completely. It's hard to tell from the screenshots but as I move the camera, I noticed her body looked a bit shiny or metallic (or wet) which isn't right.

I believe this could be fixed if I figure out how to do parameter (prm) textures correctly. This is important if I want the texture to correctly reflect the game's lighting.

 

Since this model also uses its own skin texture, I tried to make my own skin material as well so it could reflect the game's lighting properly but due to the lack of the aforementioned texture maps, the texture can reflect light quite poorly depending on the lighting.

 

Also depending on the lighting, it could look fine as well.

 

 

So yeah, I figured out how to apply the fur shader correctly but I still got some kinks to iron out with the materials to reflect light properly.

If learning how to make texture maps is all it takes to make a high quality nude mod, then so be it. I mean hey, that's a pretty cool motivation to learn if I say so myself.

Okay, I just discovered the reason why Amy's skin had that bad glow.

I've looked in the Hedgehog Engine Modding Discord server again and according to the people there, the game just has shit subsurface scattering.

That's really it, and you could probably tell by looking at Sonic on the previous post. His belly shouldn't be glowing like that and I haven't even touch his model or textures.

It can be disabled so Amy's nude model with the skin shader applied can look normal in any sort of lighting.

I also made my own prm textures and I think I did it right, her body doesn't look like it's reflecting like metal. I might be done on polishing her textures!

So I guess all what's left is make the variations again with the navel and pussy colour edit and have it replace all Amy's models (cyber ghost, original, birthday, and playable). Then afterwards, do another version with the cyber ghost shader effect to make it story-friendly too.

Good to know. Playable would be awesome, too, if possible.

[Catnatic]

I got a surprise for those who prefer ShawnGuku's nude model of Amy!

 

 

Moving and renaming "chr_amy.model" to "chr_amyP.model" along with the textures and materials to "amyP" folder and convert it to .pac format surprisingly works fine with the animations looking pretty normal as one would expect.

Just plop this file to the mod's files where "amy.pac" and "amy_orig.pac" are and it should work as part of the mod.

 

The file address should be like this:

"SonicFrontiers\Mods\Nude Amy\raw\character"

 

Download:

amyP.pac

 

Old Version:

Spoiler

 

Download:

amyP.pac

The cyber ghost effect is probably too noisy than even the vanilla playable model though, something that Shawn would probably fix in an official update.

I'm just providing an option here to let you play as Shawn's nude Amy early so you don't have to wait for that update... if it ever comes.

 

I also made a non-cyber-ghost bottomless version too!

 

Download:

amyP.pac

 

Finally, non-cyber-ghost version of Amy in the nude!

 

New download with removed cyber particle effects:

amyP.pac

Old version with cyber particle effects:

amyP.pac

Known issue is that animations in her legs look more noticeably off without the cyber ghost shader. Her idle animation with the cards is broken too.

There's nothing I can do to fix them, that's up to the original author of the mod.

 

 

As for my own version of the Nude Amy mod that uses Smez's model, I'm very close to finishing it.

I got all the variations implemented with the material shaders applied properly for "chr_amy".

I still need to do it for "chr_amy_orig" (non-cyber-ghost Amy in cutscenes) and of course "chr_amyP" (playable Amy in Another Story) to complete my mod.

I tried to add Amy's nude body to her birthday variant (chr_amy_birthday) but the game crashes while loading for some reason and I don't know why.

What a shame, Amy would've had ribbons attached to her tits in-game if it worked. Though I could just have that as another variation for the main models.

Spoiler

 

Also here's another thing:

Before I worked on importing Smez's model, I did have an attempt at importing Ganondork's model of nude Amy to the game because I still like curvy bodies (including ShawnGuku's Amy model) as well of course, not just on-model ones, but unfortunately I couldn't figure out a way to fix her arms and boobs for animations and I don't feel like bothering any further. I'm getting tired of this game and I want to move on after finishing Another Story and of course releasing my mod of Smez's model.

Spoiler

If any modder likes to have a crack at fixing it, be my guest. Note that it's not a playable mod, there's only .fbx and textures in this zip file.

chr_amy_ganondork.zip

If the mesh is transparent when imported to Blender, uncheck "Show Backface" for each affected material and that should fix it.

I already made and named the vertex groups that matches the vanilla model's vertex groups but perhaps I did something wrong like assigning the wrong vertices maybe.

Okay, this is epic. My only complaint is that there's a bit too much static over her. Is there a way to fix that?

I made adjustments to the materials so that it matches with the vanilla playable model's cyber ghost shader.

It's fixed now, not as much static and noise anymore. Check my previous post, I updated the downloadable files.

I even added a non-cyber-ghost bottomless version too.

Some fully-animated cutscenes may show Amy having a twisted body.

This is probably because her dress is meant to hide it so the animators don't have to bother fixing it.

I'm not sure if there's anything I could do about it.

No, I was wrong. Any cutscene that shows Amy having her pelvis twisted is simply due to the fact that it was missing a "Pelvis" vertex group.

Well actually, the model already has a vertex group surrounding her pelvic region but it was named incorrectly.

I went through the trouble of trying to fixing her other vertex groups and weights which broke the animations, only to realise I just needed to rename a certain vertex group so it can be recognised by the armature's pelvis bone to fix her pelvis from twisting.

This is why I still haven't release the update to my mod yet, I wanted to get that issue fixed and I finally did it.

 

This is what it looked like before:

 

This is what it looks like now:

So much better. Too bad the glitch effects obscured it a bit in the screenshot, but there's nothing I can really do to remove them.

Anyway, now I'm very very close to finishing my mod that I might finally release it in a few hours!

Awesome! Looks much better now, ty for the update! Would there be any chance of getting a version of this with the static removed completely like the bottomless variation? If not, no worries, but I figured it couldn't hurt to ask.

I actually tried doing that a couple hours earlier but I had some trouble.

At first I planned to use Shawn's "chr_amy_orig" model except I just remove the dress. Unfortunately, importing that model to Blender breaks the UV map so I had to do something else.

So I tried to use Shawn's "chr_amy" nude model instead except I remove the cyber ghost shaders.

I wanted to retain the fur shader but it turns out the body is using the same material that Amy's head uses, unlike the model from "chr_amy_orig", so her entire body including her arms and belly are now furry.

 

 

Her legs aren't animated properly either and there's nothing I can do about it since importing the model to Blender adds more problems, and I'm already tired of fixing vertex groups and weights anyway.

 

 

So I decided to just screw it and make some compromises by using the skin shader which retains the detail of her body but her head loses the fur shader that the vanilla model had.

 

I'll update my other post with the new download shortly. You're welcome.

Thank you! Shame the legs are being a pain, but I'm fine with "good enough," and it was really nice of you to do this, especially considering you're busy with your own variation. Thanks again!

[Catnatic]

I believe I'm finally done finishing my mod!

All variations have been implemented, and I even added a "birthday/party" variant that is supposed to replace the "chr_amy_birthday" model but couldn't.

I never realised how shiny and detailed those ribbons are since we could only see them with the cyber ghost effect in the vanilla game.

 

 

My mod not only replaces the cyber-ghost Amy you see on the Open Zones but also the models for playable Amy (above) and non-cyber-ghost Amy (below).

 

 

I also made two adjustments when I was finishing my mod:

First one was rotating Amy's tail UV map so that the fur on her tail is brushed horizontally (left) instead of vertical (right) which I think looks better that way.

 

 

The other adjustment was shortening her skirt if she's wearing a dress.

 

 

I will release the latest version of my mod soon once I made some thumbnails or 'promo' images for it like I did with my other two mods, because I care about presentation.

[Catnatic]

After like two weeks of active development, I finally present to you my version of Nude Amy!

I'm calling it "NSFW Amy Pack" to differentiate it from ShawnGuku's mod and because you can customise Amy's level of exposure.

It comes with seven options to choose from including naked, underwear, bottomless, short dress, and more.

 

Thank you to Smez who originally created and publicly shared this nude model of Amy, which I made some slight modifications to.

 

 

You can download the mod here:

Mirror: https://drive.proton.me/urls/3ZXY679N98#S51cNhzGOKVn

 

The reason why I didn't announce this here right after uploading my mod was simply because it was very late for me to stay up at the time.

I need to take a break after this, it's what I've been doing for most of my time the past couple weeks and now it's finally done. I can now rest.

I already have Ganondork's model of Blaze. I could import her to the game but I'm already exhausted from trying to mod in nude Amy so I won't do anything for a while.

Hello, is there a possibility that you can make an extra skin with Amy's body entirely pink?
