Depends which server you're connecting to. On a prebooking server, you pick the choice of skin in singleplayer, then go to multiplayer and book a spot, it'll use that one. On a free entry server, you get the first open slot and cannot choose. If the server is using a CSP mod then you can also pick your colour ingame but it's only from solid colours.
Click the lightbulb icon on your chatbox. I believe it's called "Extras".what is that mod called? because i can't change it...it does say on the server that u can change the colors but i just can not find it sry
Tnx in advance
