Additional Resources Mod 1.12/1.11.2 adds loose resources to the game without needing the user to install a texture pack. It is mainly designed for mods that have user-defined content that needs to be loaded as a resource. It has no GUI itself.

Usage:

The mod will create a directory (or you can create it yourself) next to the mods directory called “mods-resourcepacks“.
Inside that folder, put what would be in the assets folder, except for “pack.mcmeta”. e.g. “assets/mymod/lang/en_US.lang” => “mods-resourcepacks/mymod/lang/en_US.lang”
