It looks like I am on 1.00c.  Still no luck.

to help us help you, please give a lot more detail. What you did, what files you copied and where to, if you already installed any other mods, etc etc.

I am pretty confused, but there are two workarounds. One thing you can do is to wipe your install, then install the PS4 icon mod the regular way (copy in the files directly from GitHub, do NOT use my 0x77777777.yumiamod.json file). Once you verified that is working, then install my mod and future mods using my method. My tool will treat the PS4 mod as if it were part of the base game.

 

Another method is to use fdata_dump from DeathChaos25 to extract the actual .g1t files from the mod. Then use the g1t files to remake the fdata file using my scripts. With the new fdata file, it should be fully compatible with my tools.

Step 1: I tried your first idea (wipe the install...). Then loaded the PS4 files (all three). The game loaded (no nudity). So far so good. But...

When I gather (by tapping triangle) it works. However, the on-screen prompt is the square. See pic.

Step 2: Then I loaded your mod. It worked! Nudity and PS icons. Yay! But the square should be a triangle. Tapping the triangle completes the task, so that part is correct. It's the GUI that's off. Any ideas on that?

I dunno, do you have steam input or something? Maybe your buttons are being remapped. If you like your actual layout, you can edit the texture to match your layout.

I added pubic hair to the textures of amorrow28's nudemods, but when I started the game, the texture of the model was strange for some reason.  The arms, buttocks, thigh border, etc.  I haven't made any changes to the model or the other two textures that appeared.  I wish I could find the cause...

did you make sure to pack all 6 textures? I believe the fdata in my mod has 7 files in it, 6 textures and one g1m file.

Yes, that is a cloth mesh, which is also known as a 4D mesh. You can import the transformed version if you find it helpful, but please understand that we cannot edit cloth meshes. We can only keep them or delete them.

I would like to express my gratitude for the advice you have provided.

In my experience, this game has a more complex structure than other games from the same developer, such as "Atelier Ryza 3" and "Atelier Sophie 2."

I am planning to take my time and carefully work on modifications.

I am truly grateful for your insightful analysis of this intricate structure.😄

When I unzipped the fdata, there was only one g1m and three g1t files, but I can't find the remaining three...  

I would appreciate any advice you could give me.

 

 

That is very strange.  It seems fdata_dump encounters an error with my file.  Anyway, here are the build files so you can rebuild my mod from scratch.  I give permission to everybody to modify this mod, and to post mods derived from this mod.

 

v1.2 build files:  (all 4 women now available, also small fixes on Yumia)

 

YumiaNudeModBuildFiles_v1.2.7z

 

v1.1 build files:  (fewer textures, DLC costumes can be used)

 

YumiaNudeModBuildFiles_v1.1.7z - OBSOLETE

 

v1.0 build files:

 

YumiaNudeModBuildFiles.7z - OBSOLETE

(For anyone looking for the finished mod, it is here: Yumia Nude Mod.)

I fixed it a little.  

I modified the light armor of the Islay a little to make my chest bigger.

 How to install. 

Place yumiamod.json and fdata in Atelier yumia\Motor and run "yumia_mod_insert_into_rdb.py" to replace root.rdb and root.rdx.

I loaded this (as described) but she still has on the same outfit. No visible change to show your mod.

Here's a strange one.:  I installed this file (Isla_light armor) from @gggnog above. Everything works as it should now. PS icons show the correct on-screen glyphs for the assigned prompts. Nudity for Yumia. But his mod doesn't work. Go figure.

Exactly. Doesn't seem to be working.

Thanks so much @amorrow28 for the tools, they are very useful.
I can't believe you were able to develop them in such a short time, you're a genius, @amorrow28👍

 

Yumia's legs are just too long, I don't know why KT designed them that way.
Ryza's legs are long too, but she has thick legs and a big butt, so the overall look is ok.
In contrast, Yumia's butt is small and looks disjointed.

Some people might like that kind of body, but I don't.

So I made this mod to slightly modify Yumia's body to look less weird.

I am experiencing some difficulties in resolving an error that I encountered during the import process into Blender.

 

When I asked AI about it, they said,

"The code assumes that the number of elements in blend_indices and blend_weights are identical, but in fact one of them may have a different number of elements."It seems that the script is the cause,

 

but I am not entirely convinced since no one else has reported this.

Could you please advise what other potential causes might be responsible for this error?

 

The environment is Blender 4.2.8LTS and Python is 3.13

(The python path is going through.)

 

 

The blender log is as follows

Python: Traceback (most recent call last):
  File "C:\Users\myname\AppData\Roaming\Blender Foundation\Blender\4.2\scripts\addons\blender_3dmigoto.py", line 2531, in execute

probably that version of 3dmigoto script isn't updated for blender 4.0 try the one from here https://github.com/leotorrez/XXMITools

Here is another mod for Yumia!  This time she is wearing her jacket and shoes, but is still mostly nude.  This mod uses a nude mod I ported from the legendary Moderchan, of whose mods I am a huge fan.  Disclaimer: Obviously I do not own and do not claim ownership of any of the assets used in the making of this mod.

 

Update: This mod now includes all four women!  This version is for PC only, for other platforms see here.

 

AtelierYumiaRevealingMod.7z

 

Yumia_Half_Nude_v1.1.7z - OBSOLETE!

 

Instructions:

Quote

 

Copy the contents of the Motor folder into the Motor folder of your Atelier Yumia folder, and run yumia_mod_insert_into_rdb.exe (included) to inject the mods into your root.rdb and root.rdx files.  (I recommend starting from a fresh install.)  See instructions here on how to install mods and combine mods.  If the game updates and the mods disappear, do not just run yumia_mod_insert_into_rdb.exe again - first delete root.rdb.original and root.rdx.original and then run yumia_mod_insert_into_rdb.exe.

 

You are welcome to use the Yumia Easy Mod Manager from @MangetsuC if you want.  However, because my mod has variants, the mod manager gets confused.  (It is also out of date, as the root.rdb and root.rdx files it comes with are old - so the files in {mod manager}/backup need to be replaced with the most current version...)  If you want to use the mod manager, do the following: 1. Press "Import mod file" and select AtelierYumiaRevealingMod.7z (download above), 2. Press "Open mods folder", go into the AtelierYumiaRevealingMod folder and delete the Variants folder, 3. Press "Refresh mods list" and now you will see 4 unique fdata files instead of 8 duplicates.  Finally you can select the mod and enable it.

 

If you want to remove the plush doll on Yumia's hip, grab this mod here.

 

Notes:

This mod will destroy the palette swap DLC clothes, but other DLC should mostly work (interestingly one of the color swaps for Isla and Lenja work).  For Isla, Nina and Lenja, there are variants with the full skirt. For Yumia, @cyn_mod devised a configuration that worked to preserve the belt and hair ornaments, thank you to cyn_mod!  Her variant is the original without the belt and hair ornament.

My other Atelier mods:

• Atelier Ryza - Summer Mod
• Atelier Ryza 2 - Breezy Mod, Summer Mod, Fully Nude Mod
• Atelier Ryza 3 - Summer Mod, Fully Nude Mod
• Atelier Sophie 2 - Revealing and Fully Nude Mods
• Atelier Yumia - Fully Nude Mod

 

Enjoy!

Yumia_Half_Nude.7z 8.37 MB · 39 downloads

 

Instructions:

If you are using this mod alone, then backup your Motor/root.rdb and Motor/root.rdx files, then copy my files in.  If you would like to use more than one mod (who doesn't??), please use my mod install system! A .yumiamod.json file is included, see instructions here on how to install mods and combine mods.

 

Notes:

This mod will destroy her other equippable DLC clothes, because I had to replace the skin texture - when you want to use other costumes then please temporarily remove the mod.  I have not found a way to add new textures.  Also, I really wanted to keep her hair ornaments, gloves and belt; I spent hours trying but every attempt to add new meshes resulted in the game crashing.  So I had to use those slots for the body itself.  If anyone successfully adds new meshes and can explain what I am doing wrong, I can update this mod.

 

Check out my other mods: Yumia full nude, Yumia bikini (test model), Yumia's skirt delete.

 

Enjoy!

Thank you for your hard work man. You're amazing. Hope u still continue make more mods for this game. Cheers!

I created a conversation portrait mod for Yumi Nude mod.

 This is a finished product, but there are a total of 11 patterns.  

Place yumiamod.json and fdata in Atelier yumia\Motor and run "yumia_mod_insert_into_rdb.py" to replace root.rdb and root.rdx.

 

The quality is not very high, but if you like, please use it freely.

 

 Supports 2K textures.

Umia_Portrait.rar

Does this only work in HD (1080p)? I run the game at 4K (2160p) and it is not showing up like your screenshot.
