Oh loool sorry for not mentioning before ALL of my models (as of right now) are specifically meant for blender 4.1, and they are pretty hands on so if you want to do specific things with them like swap outfits, change colors, or even handle shapekeys, you have to have some good knowledge of blender to do so, adding UI's or fancy stuff makes the blend file performance ass for me and im sure it would for u guys too also i dont feel like coding so lol.
if you enjoy the neuman model consider pledging on patreon i will be putting WAAAAY better stuff on there in the future <3 (tht goes for all of you lol)
