Atelier Yumia The Alchemist of Memories nude mods request

[xlegendgame]

this game got a demo and i't running on DX12 so maybe it's not moddable but got some hope for some good mods .

[oaktree10]

Can't wait to see what mods we can get. Although imo the new protagonist is a big step back in terms of design from Ryza, but she is a far more interesting character.

[hilbo75]

looking at the files makes me think the engine might actually be different this time. though traditionally gust tools has needed to update for pretty much every new atelier game anyway so maybe its just a matter of waiting for the tools to come out like usual.

誰か、.fdataの編集の仕方知りませんか？

 

Does anyone know how to edit .fdata?

 

I tried to search in the web but no way to find info about these .fdata. I have already saw in the past but I don’t remember where. 

[assassin394]

Not a fan of anime game but I will try this out for science reason.

I hope this tool helps everyone.

Until we get some proper mods I'll have to rely on inferior artificially generated videos to get what I want

Thanks. It seems similar to Rise of the Ronin. With this tool you can extract the files but then you need a mod loader to put the modified files in the game. We need to wait someone can create it specific for this game I guess.

EDIT:  I did figure out how to mod this game eventually.  My nude mod and partially-nude mod are here:

 

• Revealing Mod - the mod pictured above with all four women
• Fully nude mod - all four women, fully nude

 

Original post below:

 

It's possible to get the models out, but the files are kind of a mess.  It's possible to find stuff with fdata_dump, I did find Yumia this way - a34c62fc.g1m (base outfit) / 66701eba.g1m (no jacket) / 3c9cc105.g1m (bikini or underwear or something, not the DLC because it is very basic, I actually think this is a test model).  @jmedia7 helped me out here and alerted me to qrdbtool (packed with his rise of the ronin mod loader) by vagonumero13, which lets you extract files with their proper file names.  a34c62fc.g1m is actually pc00_00.g1m, 66701eba.g1m is pc00_02.g1m and 3c9cc105.g1m is if00_00.g1m. EDIT: Real filenames were taken out of the full game, and are in the demo only!

 

 

The textures are kind of a mess though, I'm not really sure what's going on.  The g1m file points to 77 different textures (all sorts of effects like emission and occlusion and whatever - each base texture has ~8 files and the eyes are special too), but unlike prior games there isn't a single g1t with all 77 textures.  Instead each texture is in its own g1t file.  I believe the textures are linked via the ktid file (e.g. pc00_00.ktid for pc00_00.g1m), but the hashes in the .ktid file do not match the hashes in the .fdata file.

 

Anyway, I have no idea how this game will actually be moddable.  A loader similar to DOA6 / rise of the ronin / dynasty warriors origins is one way (vagonumero13 takes commissions but I have no idea what the fee is - I’ve been told it is high though).  The other would be to figure out if .fdata and .rdb files can be modified.  They probably can be, but there are some checksums I understand inside .fdata and some I do not.

 

This is the test bikini model (or model used for an event, I don't know).  It actually has breasts underneath the bikini, but no crotch.  I mainly think this is a test model because the hair UVs are off, but also her bust size seems to have been smaller during development...  (EDIT: Actually I think I was supposed to use testpc00a textures, those fit better.)

I must admit that I am a complete novice when it comes to tool development and cannot make a meaningful contribution.

I know that this is a very sincere request, but I strongly hope to receive guidance from “amorrow28-sama” again!

That bikini outfit appeared in ryza3 too, with exactly the same clothes and shoes. It has been used in the onsen event in ryza3.

i second this. i hope this would be possible, i'd be more than happy to test it out and help with any possible bugs.

it sounds like cynmod on twitter is going to make a freecam, but wants to wait until the photo contest is over so nobody uses their tool to cheat the contest (since that would give KT an excuse to get angry about people making mods again)

BTW, gust_tools got an update for yumia

I would like to try to make a mod that swaps the controller glyphs for the Playstation's ones. I managed to extract the .pak and .fdata files so far but am stuck at this step and wouldn't know how to reconstruct them after anyways, so for now I will be following this thread with great interest!

Someone already managed to make a PlayStation button prompt mod for both PS5 and PS4 styles if you're interested. I'm also using my Dualsense and mapping gyro to mouse and set it to activate whenever I hold L2 to aim Yumia's staff. Now the game on PC feels really good with PlayStation controls.

Any advice on how to import glm files to blender? I've managed to extract all of the fdata files but have no idea how to work with .glm

Someone knows how to write to these files but there's nothing in the README as to how to edit rdb, rdx, fdata etc??  No links to anywhere else either.  Is there a modding discord for this game, or dynasty warriors or something?

 

Edit: I messaged the mod author who did write back with helpful info. (I had already figured out a different solution but I still appreciate anyone willing to help me!)

yeah, gotta have to wait for a few more months. even then, his camera in terms of function is a bit limited.

[amorrow28]

 

I'm starting to figure out how to edit these files, and I have a "quick" test mod for people to try!  Here is Yumia, with her skirt removed.  Backup your Motor/root.rdb and Motor/root.rdx files, then copy my files in.  Disclaimer: Obviously I do not own and do not claim ownership of any of the assets used in the making of this mod.

 

Yumia_NoSkirt_beta.7z

 

0x88888888_unskirt.yumiamod.json.zip

 

No tools for other modders just yet, I'm still thinking about what to do.  Also, this is not (yet) compatible with other mods that alter root.rdb/root.rdx.  Maybe I'll be able to come up with something.  EDIT: I came up with a solution, see link below.

 

(Thanks to @Arrowed Sword for pointing us to the ps4 button mod, I tore that mod apart to figure this out.)

 

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! Download the .yumiamod.json file above, see instructions here on how to install mods and combine mods.

 

Check out my other mods: Yumia partially nude, Yumia full nude, Yumia bikini (test model).

 

Enjoy!

i use gust_tools extracting PACK00.pak reveals the folder master\cmn\fixed_data\camera, where some limit parameters can be edited. However, I haven't found how to make the character not disappear, and I don't know where they put the check for the XYZ look angle
