As you can see, the penis from alternative.futa stopper doesn't match with OniEkohvius's Mei skin tone. It's all at white color, but it still doesn't match Cant go any whiter than that... any suggestions?
You can swap the textures out in the tab at the top right. Weebuvr made some conversions to work with altfuta to match with popular female skin sets. you may want to use the normal/specular/gloss maps from those to blend things together. There is also a futa conversion for mei by Shioro, which you could use the gens texture from.
futa conversion of https://hub.virtamate.com/resources/mei.22789/ And thanks to @immyneedscake for the 2B genital texture. Used that as a base. I take female to futa texture conversion commissions now.
