mejiro mcqueen nude racewear
model edit by jmedia7

but why her again? i donot have other racewear, most are common on 2 star

Damn great job that was fast. This game has potential given the idol segments as well

[DyonisXX]

So because it's unencrypted, installing the mods is just dragging them in, right? Wish I could test that it works but I don't own Mejiro yet

 

Edit: I saw her in a random race, mod works

Replacing a Texture literally only takes like 5min, if you ignore the time you spend for redrawing (for example, the Swimsuit Texture is shared by several horses based on Skin-color and "Size" group).

2* are shared model & texture

Would it help if I made a script that parses the List from the "Copy Path" Button (under the list in [Loaded Assets] of the UmaViewer) and copy all assets into one Folder (or rather, the respective Subfolders for easy restoration)?

[dgainey]

UmaViewer is malfunctioning for me, main body/face and one other tx is not rendering. 

Any help?

[x2oa]

Is there a way to use these mods in the Japanese version?

Are you going to make mods for 1 star and 2 star characters?

I probably don't want full nude mods...but a lot of these outfits should totally get some edits and show off some more skin...maybe increase the jiggle physics if that's possible. xp

 

Like those swimsuits, all of them being one pieces, I don't know if you get other options for that, but we should replace them with bikinis instead. lol
