No, i mean his armour from campaign, its different from mp armour. I tried to do it by my self, but the armour appears without textures. Also replacing mp armour with warbass freeboot mke campagn warboses's armour without textures too.
P.S. I replase warboss's big horn with freeb armour and all work well exept his helmet, it's not replaced with freeboot's helmet.
