For those who convert models for MMD, do you already know what I'm talking about, no? Well... I want to speak precisely of the texture, for my part the hair of the model was in only one material. i wanted to give something cleaner and more natural but i didnt succeed the first time even trying with various SPH. I ended up quickly giving up, believe me... today I tried the "arisumatio" method with the following trick - https://wiki.nexusmods.com/index.php/Splitting_meshes_in_Blender it already seems a good result! I then reworked the texture of the hair, for the moment it's not yet perfect but it already gives a start. I still have to finish tidying up the materials to avoid it being strange as in the picture.
