I think Wings can be placed on armours via the Effects system.
I assume if it works how I think, you’d do the following:
1:Insert a lib with wings into the effect folder (5.lib) for example.
2:Locate the armour you want to attach the wings to and insert 5 into the Effects box in the items database.
3:Check offsets and adjust where needed.
It probably won’t work like that but I’m sure there’s plenty of people with the knowledge here to help.
