Sadly it didn’t work when put under skintones/skin details, as the specular disappeared then, idk why. And it works for toddlers-elders, female and male sims alike, + HQ compatible!
Also it has a very nice reflective shine, I really like the glossy effect and it makes the thumbnails and presentations neat and polished looking (literally, LMAO forgive me I love dad jokes). It comes in 20 colors (10 greyscale tones from white to black), and some fresh and fun nuances. Cause this item here works like lacquer, or similar on sims. You can alter faces and bodies however you want, btw. This tool works for almost all items, like accessories, clothes, hair, body or face presets, poses, etc… Only makeup gets covered up, but I guess most people wouldn’t want to present makeup on mannequins anyways hehe. I’ve made these so I can neutrally present my CC, to focus on it without any distractions, a.k.a the sim, but I figured out that some of my fellow creators (and a few people who might want to play with mannequins) could find this item useful, too.
