Umamusume: Pretty Derby (Steam)

[anon-anton23]

I'm new to installing mods. Can anyone help me install a mod correctly? I'm a Steam user on the global server.

[einnarr]

Have there been any major updates to the Steam version...?

[Dashchao]

To add to the questions, does anyone know if/how we convert japanese mods to the steam version? I have like all the japanese ones downloaded from early thread but i don't know how to make them work with steam version or if it's even possible.

Use UMPD ( https://gamebanana.com/tools/20289 ) follow instructions and the rest should be self explanatory.

You would have to manually find the corresponding Asset IDs from Global and rename the files one by one

regenerate mesh & re-replace texture (if same unity version then use raw file)

Thanks to the great Tool creator, umaviewer works, so I can file dump and edit, but UMPD packing and unpacking doesn't work, so I can't run it as a mod...
Are steam users okay ?

EN users okay
DMM changed path to game dir
idk about JP steam

[einnarr]

Tried it with reference to a great tool creator,
I don't understand the structural differences or production steps between a working MOD and a non-working MOD...
I don't know if I need another special tool or if I don't have enough knowledge...

Help me put here, I tried to load this mod in but Rice Shower and other horses are still clothed in uniforms. 
Here are my configerations. I’ve installed it in the right place, and I’ve changed all the settings, still no good.

the uniforms cannot be changed and anything with a chibi version cannot be changed with this mod, they need a seprate mod using the model thats linked to the chibi. XD

I looked at the file path, but are you a DMM user? 
If so, these mods may not work.

Don't remember if someone did the specific tutorial for finding the models and textures in UmaViewer

 

Instruction pictures:

You can click on the "Loaded Assets" individually which will pop up a folder with that one selected or you can mass export with the "copy" buttons. Also, if you load more than one model without closing and reopening UmaViewer, all of the previous ones will be listed in "Loaded Assets."

be careful that skin 2 & 3 don't have texture

nvm I fixed that but how do I change this outfit and what outfit is this? changing the winter outfit works fine but the summer softlocks

[FrenchFryFrank]

Does anyone know how to lock the chibis to use a certain type of dress or skip drawing them completely? I believe they cause a hard lock when I swap race outfits with casual outfits in UMPD mod loader and the chibis then try to find the body of the wrong one. 

If I could somehow hard code them to always use the type that does exist or just skip looking for a body in the first place, I can swap casual outfits with racing ones and not get locked whenever I hit a loading screen with a chibi

I tried hooking BepInEx for script changing but I could not get it to be successful

Alternatively, does someone know how to completely reskin the racing mesh? I only know how to modify the original for my current mods. Or maybe know how to alter the code to draw a different mesh?
