To have hats mod working correctly, u must get a Hat profile folder and replace it with that "Hats" folder in the modpack files. Same process if you're using server files.
Installing a modpack using the Technic Launcher is easy. If you don't already have the launcher downloaded, visit our download page to get the latest version.
Type in the modpack name (Official DerpeeJesus MoonPack) or paste the following url into the search box.
Finally, click Install at the bottom right of the launcher after you select Official DerpeeJesus MoonPack from the list on the left. The launcher will handle everything else!
