i have a character mesh and i wanted to replace its skeleton with another similar skeleton. so i exported the character from ue4 to ue5 and made some adjustment to its skeleton and then imported the character back to ue4. now everything works fine but character’s original material would not apply correctly to the mesh anymore.
this is the original character with it’s material 
this is the character after skeleton changes with the same material
and this is the material it self(all of the texture of the pack is in on material)
by the way i dont know much about UVs or materials so any help would be deeply appreciated.
