Umamusume: Pretty Derby (Steam)

[DyonisXX]

 

This is what happens when I run UMPD ML 121 + Ume Decryptor that was uploaded 4 hours ago on github, either way none of the old mods load so maybe it's not a big deal

uhh can i check if im seeing this issue, its because the mod files are not updated to the 2022 unity version as per the mod loader description that mods before 11/11 will not work?

No

Time to adjust my custom build of UmaViewer to re-export my mod to make it work

[Muffination]

Works, here's my update in case anyone wants it (changes several costumes to Swimsuit and replaces its texture accordingly).

MOD.7z

[icycookie]

just a quick noobie question about making mods
how do you know what is the exact file that needs to be changed? like in umaviewer we can see the loaded assets and export models and all

but when using the export model, i get the PMX file, but i do not know what is the original file that contains the FBX files or the texture files, for example, how do you find out that the file KV7HELVMKILV3GU2ZTAF6IELWKPSH26S needs to be edited?

the scrambled names, along with umaviewer linking to the encrpyted files, and the updates changing the file names makes old file names irrelevant

edit: kinda found a way when i was brute force comparing files 💀
on the umaviewer -> go to the loaded assets -> copy all
if the edits are only done on the body, the only files that are concerned are the mtl_bdy, pfp_bdy and the tex_bdy files for the different weathers
clicking onto the unscrambled names in umaviewer (eg. mtl_bdy1032_00) leads to the scrambled names so just copy over and change the unscambled file's name to the scambled one post edits/updates/etc.

tinkered around and found out the hard way

Now that everyone kinda has a handle on things with the new update, I’m just gonna mention one more time, I am looking to commission some nude or half nude Uma mods. If you or someone you know takes commissions please feel free to reach out to me, I’m looking to have a few done at minimum

I’ve been working on some half-nude mods for global and I wanted to share a few of them. 

 

This started as a fun personal project, and I’ve been putting a lot of time into creating new versions of the characters. Right now I’m focusing on half-nude mods but I want to expand into custom outfits in the future. 
 

If you like my work and want to see more, I’ve set up a Patreon where I’ll be posting regular updates, early access mods, and future projects. Supporting me there is totally optional since I’ll still be sharing some things for free here and on gamebanana as well.

I just made a fork of UmaViewer that adds me a button for
- Read in all files in a selected directory
- Associate each file with the one from the Asset Database 
- Reexport the file with whatever name & encryption the target file had

That way I don't have to care what they are called nor what encryption exists

Will you be making your fork public?

updated UMPD Mod Loader
You don’t need to prepare encrypted assets—UMPD Mod Loader will handle them.

would this work to port over the japanese mods or would it take more to make those work?

updated UMPD mod loader

- automatic download requirement if not exist

- added cutin dropdown in training settings

 

anyway

i regenerate mesh & recompile that teio v2, i'm not gonna share, just wait F4de update

[RaidouPanda]

Do any mods exist that replace the training swimsuits with traditional school swimsuits? (basically just trimming off parts of the bottoms instead of them being shorts) As well as replacing the towels in the hotspring sections with nude mods (but not full nude mods everywhere)?

[Fuwalos]

Anyway to use the old towel model/textures before the update happened? The new towels seem whiter and less opaque while the old ones looked wet and you could see skin bleed through in areas that hugged tightly.

Someone made the swimsuits in the JP version. Sadly, I can't find it or anything equivalent for Global

Hello, how do I change all uma horses to wear backup dancer costume, like on the beginning screen and such?

reason why is I founded a mod on discord that changes all horses’s body to nude without sacrificing body type, but it only shows in training and concerts.

you can use UM:PD ML

[vetazombislayer]

Yes, I have the modloader, it’s up and running but I’m not sure what varibles to change to under one of the options. 
Under dress settings right? It says 7- backup dancer, but I’m not sure what i should change under gender, body, sub and etc.

find dress u want then change to these value
body 6

sub 0

body setting 2

head sub 0

 

if not work then change body setting to 0

[vetazombislayer]

As you see here I have it set to the value you posted but the horses are still in their standard academy clothes on lobby screen. Anything I’m doing wrong?

i clicked on save all after changing calues, and I’ve tried this game with both true and false settings under gender. I’ve tried the value for body at 6 and 0.
