I might just be stupid but i can't seem to get the model swap button to show up in the GUI, i'm running the DMM version.

 

i dont have the dmm version but it should be on the top left side of the GUI

 Does anyone know where I can get this mod? I can't find it anywhere.

 

 

use the MISC-> character -> proportions -> bust set to 0~4 for your liking

it works perfectly fine for the normal outfits like uniforms, gym and swimwear

however, it will mess up modded bodies texture if for example you are using f4de's mod for teio's unique racewear, as it the texture is mapped to the specific height shape n bust

Sorry, it's me again, but does anyone know where this mod came from? Is it a mod, or is it some other kind of mod injector? If you can't open the link, it's the one where Satono, Kitasan, Loves Only You, and Rein Kraft have some pretty... prominent melons.

just change the bust settings to 4 and you are done

If you mean that the breasts bounce significantly, adjust the CyspringParam...

three CySpringParam values need to be adjusted,

 

Stiffness Force:shaking strength and speed

Drag Force:shaking resistance magnitude

Gravity:Min value

 

For example, Eishin_Flash breasts jiggle more than those of other characters.

 

Stiffness Force:"150(Standard)" "400 (Eishin_Flash)"

Drag Force:"400 (Standard) ""600 (Eishin_Flash)"

okey, and where i can find that, and what type of % to get ban for doing that?, Also, when I set the breasts to level 4 and try to set up a concert, the game gets stuck on the loading screen forever. What else do I need to do? Sorry, but I'm new to modding Umamusume, and there aren't any visual tutorials. Thanks for responding and for helping me.

interesting, how do we edit those?

[Mawliina]

also a quick mod idea, since i can't do it myself as i lack the knowledge, maybe someone could remove the undershirt on the uma summer outfits?

[einnarr]

What is the process used by the people who create the base body?
tri it, but I don't really understand it...
limbs and fingers are disintegrated, and the texture of the base and controls are also painted over to disguise it...
Still, it has taken shape, so please try using it if you like.

Never mind the location—I already know where it is—but here's another question: how do I change it? What app do you use?

It is simple to write directly with an asset editing tool such as UABEA.

Cyspring is set for each Uma Musume model's head, bust, and skirt.
It may be faster to search for assets from umaviewer.
Or...if you don't mind using external tools,One way to do this is to use UM:PD Hachimi to enhance graphics and release FPS limitations.

Hi, I was wondering if you could guide me on how to modify this. I’ve spent the whole night researching but still can’t seem to find the right method. I’ve successfully managed to unlock the FPS, but I’m stuck on the rest. Would it be possible to provide a guide or even a pre-modified file? I would truly appreciate your help.

I've been looking into it too, but I can't seem to find anything. Can I ask how you unlocked the FPS, and if it's caused you any problems, like getting banned?

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.
