Apologies, I ought to have been more clear.
I mean, the shields and armor that normally show the flags such as Kite Shields and Herladic armor with long surcoat, etc. are not working for my two new factions. This tutorial shows more how to add those meshes to other gear that normalyl does not have them. However, I could try making another exact same version of the item and just give it to those certain troops. I'll try it out then let you know.
All of the lords now have totally different shields too. Like, Ragnar has on his flag and his background information the Nord banner with a raven on it, but all his troops carry the Vaegir faction shield (panther). hahaha frustrating.
