the directory is simple but the hard part is knowing the folder name of the armor/weap.
For armor, it's: ...data/models/armor/[armor set name]/[armor file]
and ...data/materials/models/[armor set name]/[armor file]
for weapon, it's ...data/models/weapon/[weapon file]
and ...data/materials/models/[weapon file]
do not include brackets.
e.g. blackhammer set armor folder name is "blackhammer"
raider and wonderland set is "glasgavelen"
