i assume its headmod from salvation? if it yes, there are face part on material editor that give a shadow on front of eyeball, u have to change it shaders to "studio alpha" and reduce the alpha slider to around 65-ish
but as a offer of good will here is my upiuu collection (not complete and the card below slightly edited idk where i left the unedited version but rest them are unedited) https://gofile.io/d/6KdA1h (reup)
Anyone has this new arisaka card?https://www.pixiv.net/artworks/142968528 Arisaka cards are well made, but too expensive, 5000 yen equals to my food expense for one month🥶
