Sorry, Im not sure what you mean.
Do you want to make the skirt disappear?
Well I wanted to replace Endijian's Sash by Niokaste's Cord editing "itemtype.txt" so I changed:
(Endijian's Sash) "models/heroes/seraphim/sets/ancient/c_sera-ancient-pelvis.GR2"
For
(Nioka's Cord) "models/heroes/seraphim/sets/angeldust/c_sera-angeldust-pelvis.GR2"
It worked but the skirt does not appear.
Displays only the pelvis so I tried to replace for
"models/heroes/seraphim/sets/angeldust/c_sera-angeldust-pelvisskirt.GR2"
but the pelvis disappears and appears only a "bugged" skirt between the legs of the Seraphim
