modding Modding Help: Correctly add decal overlays to new model

[kadsend]

Okay so I finally finished a very early personal version of UUNP + HDT vagina with a handmade mesh to a specific NPC... and When I started testing her and when I killed her, the cut decals of my sword appear as "swirls" on her skin... That's mildly annoying and I've researched a bit and couldn't find a proper thread that had the same issue (besides mine) the mod author of the base mesh "COSIOHD" said that they have no experience on how to fix the issue but said that it was related to the UV wrap does not match the current model (CBBE base to COSIO High Poly) . I'm asking here on how could I remake the UV wrap and fix the swirly blood skin decals?

 

Thanks
