Utilize umaviewer.
For example, if you select a common costume(15), you will have the following assets:

pfb_bdy1015_00_bust_cloth00
(pfb_bdy1015_00_cloth00 is skirt)

Rewrite this asset directly.

"Sp_Ch_Bust0_L_00" "Sp_Ch_Bust0_R_00"
_stiffnessForce 245
_dragForce 300
_gravity 10
_limitAngleMin X 25
_limitAngleMax X 08

"Sp_Ch_Bust0_L_01""Sp_Ch_Bust0_R_01"
_stiffnessForce 75
_dragForce 280
_gravity 10
_limitAngleMin X 14
_limitAngleMin Y 12
_limitAngleMax X 14
_limitAngleMax Y 12

Adjusting it to about half of the original value should double the shaking.
There is also a file, but since it is a DMM environment, it may not be possible to use it as is.

DMM_Ver.rar 6.56 kB · 19 downloads

I don't think there are any changes to the game structure, so I believe it can be edited.

Since I encrypted it for overwrite saving in DMM, I should have also included the decrypted file.
If you want to update by overwriting with the decrypted edited file, re-encryption will be required.

"Included the decrypted file" here?

UMML 1.4.2

  • added "scale" to attribute
  • added legacy setting.yml for tumugu mod compatibility
  • swap character: removed load asset & replaced with save as. thus also make work on global
  • swap character: attempt fix softlock by bidirectional normalization assets
  • load asset manual: renamed raw to manual, support platform structure mod

you can load 楪蘭楓 mod using load assets (manual)

Where in the UI will this be displayed?

It's on the right side when you select a uma. located under loaded assets. image.thumb.png.2609a22b878fc00093a6376dc1257c4e.png

Sadly I won't be able to help farther than this cus I'm also a noob at editing Uma files. But I remember someone saying you need UABEA in order to edit these files. 

 

@einnarrYou know how with the spring G1 Celebration they let you get extra star pieces for doing certain races in career? I hope they do something like that for Hishi Akebono. She got the biggest breasts in the game! And your model is so good!

Thank you!
Honestly, slender figures are also part of the charm of Uma Musume, so I understand that many people might not like this style...
There are many challenges, such as matching skin texture colors and adjusting meshes, but I want to use this as a base for editing Uma Musume with bust sizes 2 to 4...

 

I'll include the decrypted pfb_bdy1015_00_bust_cloth00 file. Can UMML load this too..?

I do prefer slender figures but I can also enjoy a thicc lady! 😁 When you said, "There are many challenges [...]" I was like, "Ooohhh boy, I've learned first hand how difficult it is to put a nude model on a uma clothed mesh." Your hard work is paying off though! Skin texture matches well!

 

One day I'll be a pro like you, Rankaeder, and Goofyahhcats! So I'm taking a small break, that way I don't get burnt out.

use "load assets (manual)"

rn platform filtering is prompt ask, not automatic
you need create "PC-s" folder and put assets there

i improve these later

I tried to put the face of Duo Svol on Mayano Top Gun, but the expression was a bit broken. After all, the face shape and eyes are different, so there is no way to perfectly map it.

But interestingly, the game didn’t encounter any errors at all.
