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?

 

You find 'Misc' in right upper cornerthen choose Character - Dress

 

Then scroll down until you find Tazuna and others, change the setting from default to False-2-0-0-0 (Tracen summer uniform) or False-2-1-0-0 (Tracen winter uniform)

For the trainee with racing outfit and racing NPC (Happy Meek and others), change to False-5-0-0-0 (Starting future) instead or you will get loading error in race.

 

Beware that the change of racing outfit will definitely cause loading error in the last concert in Grand Concert scenario so you must restore assets and delete database to default to continue. But it works normally in other scenarios.

Yay, I did it!
Thank you so much!!!

Excuse me, is there any way to increase the bouncing of the breasts?

So, using UABEA i edited the values for Jiggling, but i dont have idea of how to export to implement it back, using the UMML 

 

 

If someone can tell me how, i will be grateful

 

 

Where u get that file? are you using Umaviewer?

[girufanasu]

Excuse me, I extracted
pfb_bdy0002_00_bust4_cloth00 from UmaViewer and changed the following values in Sp_Ch_Bust0_L_XX and Sp_Ch_Bust0_R_XX:

0 float _stiffnessForce = XXX

0 float _dragForce = XXX

0 float _gravity = XXX
and reflected them in UMML, but
I can't see the changes reflected in Steam. (Even with impossible values, there's no reaction.)
I can see the breast jiggle has changed in UmaViewer, but
is there anything else I need to change? Please tell me.

Also, are these the only three things I need to change?
In this chat, it was mentioned that I should halve the original values, but elsewhere, it's said that 1000, 800, and 10 are good, so it's all over the place and I'm not really sure.
0 float _stiffnessForce = XXX
0 float _dragForce = XXX
0 float _gravity = XXX

Also, there are multiple XXs below. What do these refer to?

Sp_Ch_Bust0_L_XX, Sp_Ch_Bust0_R_XX

Each costume has different parameters that affect how it sways, so there’s no single “right” set of values.

Find the values that work best for you.

 

ex 100 100 100 sample

 

 

 

 

There’s a YouTube channel that has posted numerous music videos for “ワンダーアキュート (Japanese)” and the way the swaying is portrayed there is truly amazing, so be sure to check it out.

When wearing multiple layers of clothing or when there are multiple items

that are subject to physical forces, such as accessories,

the value of XX increases.

それぞれの衣装には、揺れ方に影響を与える様々なパラメーターがあるため、唯一の「正しい」値の組み合わせというものは存在しません。

自分にとって最適な価値観を見つけましょう。

Thank you!
Thanks to you, the jiggle motion has changed!
Perhaps the original value I specified was too high, causing no reaction.
I had replaced the character with a nude using a MOD, so layering clothes was complicated and I didn't understand it well.

I'll fine-tune it from here to find the jiggle I like!

Since I was taught this,
I'll write down the process for others who, like me, want to modify nudes and jiggle.
I tried it on the Japanese version of Steam, but it's probably the same on the Japanese version of DMM.
What you need is:
UMML ← Can be used to upload character settings, data replacements, MODs, etc.
UmaViewer ← Exports the necessary character data
UABEAvalonia ← Can be used to modify character data
Nude MODs are also discussed on this forum, so please try searching. You should be able to find people creating MODs by searching for keywords.

The process is to upload the nude MOD using UMML. (Import the entire target folder using "import Asset Folder")
For detailed instructions, you can use a translation tool or check the forum.

To make the breasts jiggle, extract the necessary data from UmaViewer (data replaced with nude data → generic clothing like 02, 05, etc.),
manipulate (~omitted~ bustX_cloth00) in UABEAvalonia, and
upload that modified data in UMML in the same way.
This is the process you can follow.

Nice  .

It would be incredibly kind of you if you could make a video tutorial so that those of us with "dum dum brains" could understand it better.

A video tutorial would be a god send! Though I wonder what upload method would be better to avoid detection from Cygemusu. Uploading to google drive or uploading the vid here?

When I use the "Copy All" function in UmaViewer to extract textures, only the wet and dirt versions are exported, and I cannot obtain the standard version. Please tell me how to fix this.
