Luke’s (Hopefully) comprehensive modpack making guide. in Platform Pagoda Posted December 5, 2013 Great thread. It's been a big help so far, but there is one problem i'm having. I've got my custom pack, and i need to do the Nei Item dump thing, but i can't get the Technic Launcher to launch my pack. I pasted it into the modpacks folder, but the launcher won't give it as an option. How can i launch my pack?
