如果您要复制原始资源，请使用 UmaViewer（已加载资源 > 复制生成的资源）。因为
这些文件是加密的，而您可以使用 AssetStudio 导出，
UMML 会在加载资源时加密这些文件 。

Hello, author. I followed your tutorial to extract and modify the mod and there were no problems during the process. However, the game won't run after replacing the model. What should I do? I'm using the hachimi plugin and putting the modified modules into mods

To decrypt you will need to use UmaDecryptor

Taiki_Shuttle.

She should be fine even if I make her thicker.

her leg is kneeling

could you fix it?

I fixed this

nude_mod.zip

[TmasinAlt]

Sorry if this has been answered, but was there a zip drop for making the training outfits (tracksuits/swimsuits) nude with base proportions?

[einnarr]

no-bikini.
Personally I prefer V-string bikini, but this one's for those who like it nude version.

Silence Suzuka's asset wasn't locked, so I've fixed it. You shouldn't run into any problems unless you're using the DMM overwrite file, but just in case.

i uploaded Image Color Swimsuit to AyakaMods

credit to RanKader for mod

 

no fixes, only UMML conversion

also White Swimsuit converted to normal assets instead encrypted. so it should work on new update

[girufanasu]

Excuse me. Could you please help me?
When I click "Import Asset Folder" or "Install Mod" in umml_151, I get the message

"〇〇 assets loaded successfully."
"0 assets were not found in meta database."

as shown in the image, and I can't do anything.

Do you know how to fix this?

I was able to resolve the issue with running UMML myself.

I apologize for asking another question, but I would like to increase the breast movement. Could you please provide any resources or instructions on how to do this?

I tried to manually replace the head mesh to avoid the chibi softblock, but even after i replace all the textures of the head this weird effect keep showing, this happens even with custom meshes, anyone have a clue of whats causing this? every help is much appreciated.

 

 

I just noticed that: Export Raw the head from Yamanine archive and Import Raw to Grass archive fixes the texture, but it breaks the rig (because I omit the step of rebuild mesh inside unity)

 

and Reimport the Grass head to his own archive fixes the rig and the texture, but is not the face of Yamanin Zephyr

 

so is not a texture issue, apparently a mesh issue, maybe it gets broken in the step of rebuild mesh in unity?

If someone can tell me how, i will be grateful

create a folder then put asset to it
ran UMML
"Import Asset Folder"
select a folder you created before
yes & conform

Does anyone happen to know which mod was used in this video?
UMA Summer Nude Mod Umamusume
It looks different from the nude mod posted here.

[einnarr]

Gold_Ship(Battled clipping...Lost)

I want to make ★1 and ★2 characters too... little by little, though.

I'm sorry if this has already been asked, but could someone please tell me how to make NPC characters like Tazuna appear completely nude?

私はこのMODを使って、MODローダーでNPCの服装を制服に変更します。

 

 

I use that mod, too.
But could you actually change Tazuna and the others' outfits in UMML?
I think I just don't know how to do it, so if you don't mind, could you show me how?
