ĪWell, what you might have is another class, such as your character class unpack the addressable and then pass it to the paper doll using the set texture method. Or build a script whose sole job it is to unpack these and send it to paper doll then just attach that script to everything that needs it. Email address is bluemanafox@gmail.com, would love to see your final solution to the problem!
P.S. not sure if we're talking about the same thing or not. Addressables doesn't use a resource folder at all, instead it prevents an asset from being loaded until it's needed whereas resources load everything and keeps it in memory. It may not work, sounds like there's a potential flaw with the dedicated server design. Depending, it may be worth it to restructure it if that's possible.
