Is it possible to change the player's skin to a skin saved locally (i.e. a skin saved on the server) so I don't have to invoke the Mojang API and deal with requests and what-not? I saw this thread on StackOverflow from years ago. https://stackoverflow.com/questions...yer-skin-to-png-from-server-invalid-signature I would like to do something similar to that, but I don't know what he means when he said that he fixed it by saving the skin's signature locally. I haven't done anything like this before and I need some detailed instructions or some examples on where to start for this. I've looked at the ChangeSkin plugin and I think it has far too many bells and whistles for what I want to do. I simply want to change the player's skin during gameplay to a skin saved locally for all players to see. No, I can't afford to buy 15 minecraft accounts to accomplish this.
