Hello JimmyRJump , Well that's not right , because I've played on a few servers that had similar mods on it without the client having to download it. Quote from another site: ( "In case you want to avoid these things, try to stick to mods that do not require install on clients or change the game files. Mods that require to change game files (mostly .dlls ) need to be copied to game install dir with(!!) overwriting exiting files. [server and client side] Mods (that only go into the Mods Folder) with "UIAtlases" & "Resources" folders need to be installed on Server and client side. Mods (that only go into the Mods Folder) without "UIAtlases" & "Resources" folders don´t, they get pushed to the client while starting the game." ) I have about 10 mods on my server without "UIAtlases" & "Resources" folder and there the client / user does not need to load them either i haven't found the right 2 mods yet or there must be a way to edit them so that the two folders "UIAtlases" & "Resources" are not needed.
