Adds increasing quality backpacks to use as you progress through the game.

About this mod Author’s original text

This is a custom.yml file with custom backpacks for use with Smoothbrain's backpacks mod. It will not function without it.

MANDATORY: For this mod to work you must go to your Smoothbrain-Backpacks config settings and turn on "Use external YAML".

If there is any difficulty with the mod loading for you, simply rename the.yml contained to "Backpacks.yml" and add it to your configs folder. You MUST do the above step and check "Use external YAML".

Thanks to JamesJonesTV's mod I was able to figure out the exact format required for custom bags to work correctly.

  • This mod includes 4 new backpacks designed to accompany your progression through the swamp, mountains, plains and mistlands biomes.
  • The backpacks have their maximum properties available without upgrading, as I currently see Smoothbrain's backpack upgrades do not work. That being said, there are 10 coin optional upgrades so you can have the bag's star level match the tier of the bag. (2-3-4-5)
  • My bag balance intends for the starting default smoothbrain backpack to have 50% weight reduction or less with the default 5x3 (15) slots.
  • Keep in mind smoothbrain's mod has a setting to have the backpacks invisible on your character if you wish. ("Hide Backpack")

Recommend using AzuExtendedPlayerInventory for a dedicated backpack slot:

For those who come after and may wonder why their custom bags had issues loading as I did; the order of backpack entries matters for several settings, and backpacks must contain an upgrade even if you don't care about using upgrades on them. Blank entries for backpack parts does not mean they are hidden. (Use visible/hidden/hexcode)

Also, in the mod config it is mentioned 8 slots wide won't work, despite it working in other mods it doesn't work here from my attempt.

Install & use Install: BepInEx plugin

  1. The archive from playbuff is the mod itself — usually a BepInEx plugin (a .dll or a plugin folder once unzipped).
  2. Recommended: use a community mod manager (such as r2modman) — pick this game, import the mod, and the manager sets up BepInEx and its dependencies for you.
  3. Manual route: install the BepInEx loader in the game folder, then drop the unzipped .dll or plugin folder into BepInEx/plugins/.
  4. Launch the game — the BepInEx console logs every plugin it loads; seeing this mod in the log means it is installed.

Mods with listed dependencies need those installed too, or they will not load. Options are usually changed in-game or in the plugin's config file. In multiplayer, the host and every client need the same mods installed.

Dependencies

Install these first, or the mod will not work:
