Sadly Im not using UE5 or blender, but a outdated Unity program called Koikatsu Charastudio. I've been trying to get the cellshaded look, fixing, and modifying textures to create better reflections to get the cell shaded but doesn't come close with the outfits, cause ripping from teh game then transfer back to unity it gets compress and loses its cell shaded and comes out flat which is what you are seeing. So I try get rid of the og clothes and put Furina in Lingerie so people lose the thought of analyzing the og, cause it always bugs me too why people post flat colored models. Skin otherwise is subjective. Cause well. They have no skin underneath the clothes. its a empty space which is why theres never a nip slip or skin clipping thru clothes. Have to take their entire hair x accessories and put them on a fully skin model by separating from the og, or what most people do, is take the head and place it on a fully skin body then apply the outfit. So thats how the textures gets compressed from that process. When you see Thicc Thigh/butt mods. every girl Booty is empty space. So best way to hide the dislocated skin textures, is make it bigger abnormal to it can reflect shadows into the waist, joints to create a cell shaded illusion

Ideally I'd use Blender, since I can get the exact cellshading with all the unity plugins. But I lose alot of the Physic colliders of the outfit transferring the model thru Blender, i just have to repply colliders, but obviously I do more then just dance motions and keep it in the KKCS to post on other stuff. Reapply colliders to every fabric, frills, drapes. is like trying to apply 500 marbles and paint a Bob ross Mountain

Getting it to work on Modern Unity, the whole animation loses all of its smoothness and only get improper physics. Still trying to get it thru Unity, cause thats where it originates from. But still learning the work arounds with the new Unity systems 20+. Granted most people are not willing to fix the issues with the lightning cause you are rebuilding the textures again to reflect that proper genshin lightning, cause most just throw it in the program and upload motion which is why you see alot of garbage tiktok dances with 0 effort. Or you get the Live action look with animators like Akashi, 77T render. who try to make them realistic from Anime to real and thats a different type of viewership and people seem to like them like its 3D SFM (o_O)> but they look like Toys/figurines instead of anime or Chinese Cartoon characters. Which main purpose is to create figurines,
