Well, it's been an awful long time since I posted my status on packing and unpacking issues, but I made it work! I recommend a batch file structured like this: Code: "C:\Program Files (x86)\Steam\steamapps\common\Starbound\win32\asset_packer.exe" "<location of mod EXACTLY>" "<location of where you want the pak file EXACTLY>" and save that as packmod.bat or whatever you want to name it, but include the .bat file type. Notepad can create batch files, so your okay to use that for making batch files. And, I don't know if anyone ever told you, but .modinfo files are out-of-date. Use .metadata or _metadata or the game won't read it. If that doesn't work, try copying the win32 folder and your mod to an external storage device and change the batch file paths respectively.
