📋 About This Mod

An Apex Legends style heirloom, and holstering your weapons: when you put your weapon away, your hands bring out a Jakobs knife and keep it in hand, with their own animations. And a key to put your weapon away.

The animations will evolve over time, and new heirlooms will be added.

WHAT IT DOES

Apex Heirloom brings two things, each with its own switch in the mod's menu.

The heirloom

  • []When you put your weapon away, your hands come back up with a Jakobs knife in the right hand, like an Apex Legends heirloom.[/]

    []The knife has its own animations: idle, walking, running, crouching, sliding and jumping.[/]

    []When your weapon comes back, your hands go down with the knife.[/]

    []The knife hides when you climb (ladder, ledge, wall); the heirloom does not work in third-person view.[/]

    The holster

    • []A key puts your weapon away: hold A on keyboard (the key to the right of Tab, Q on an English keyboard), Square on controller.[/]

      []By default, you hold the key for a short moment. On controller, Square also reloads: that is why.[/]

      []To draw your weapon again, nothing changes: do it as usual in the game.[/]

      Third person

      • []The Heirloom doesn't work in third-person view.[/]

        WHAT IS ON AFTER INSTALLING

        Everything. The mod turns itself on the first time you launch the game after installing it.

        Open the console with ~, type mods, then choose Apex Heirloom: its settings window opens, in English or French. It has three pages.

        • []HEIRLOOM: turn the knife on or off; the mode; the knife's size, from 50 to 150%; the moment your hands appear when you put your weapon away, and how fast they bring out the knife.[/]

          []Apex mode: all the animations I made for the heirloom. Borderlands mode: the Apex animations when idle, walking and running, and the game's other base animations for the rest.[/]

          []A setting change applies at the next weapon change after leaving the menu.[/]

          []HOLSTER: turn the holster on or off; hold or press, separately on keyboard and controller; the hold time, from 0. 2 to 1 second.[/]

          []CONTROLS: change the keyboard key and the controller button in the menu.[/]

          Your settings are kept when you restart the game.

          REQUIREMENTS

          The Borderlands 4 Python SDK (oak2-mod-manager). Without it, the mod does not run:

          bl-sdk/oak2-mod-manager

          INSTALLATION

          • []Install the Borderlands 4 Python SDK (link above), if you have not already.[/]

            []Download the main file Apex Heirloom, open the archive and copy apex_heirloom.sdkmod into ...\Borderlands 4\sdk_mods\[/]

            []Also download the Heirloom Paks file and copy its twelve files 000_ApexHeirloom_999_P, 000_HeirloomLists_999_P, 000_ApexHeirloomAxe_999_P and 000_HeirloomListsAxe_999_P (.pak, .ucas and .utoc) into ...\Borderlands 4\OakGame\Content\Paks\[/]

            []Launch the game. The mod is active.[/]

            With Vortex: install both files. For Heirloom Paks, Vortex asks which files to install: choose Install All.

            To uninstall: delete apex_heirloom.sdkmod from the sdk_mods folder and the six files from the Paks folder.

            ONE FILE PER PART

            Only want one of the two parts? Each also exists as a separate file, in the Files tab:

            • []Tidy Weapons, the holster alone, copy only tidy_weapons.sdkmod into sdk_mods.[/]

              []Heirloom, the heirloom alone: copy heirloom.sdkmod into sdk_mods, and the twelve files of Heirloom Paks into Paks, as for the full mod.[/]

              You can install Tidy Weapons and Heirloom together. Do not install the full mod together with a separate file: only one of the two would turn on.

              WITH OTHER MODS

              Works with all my other Mods

              WHAT HAS BEEN TESTED, AND WHAT HAS NOT

              • []Tested on game version 1. 10. 2-4845623, with three different Vault Hunters.[/]

                []Tested with a controller and with mouse and keyboard.[/]

                []Tested in solo only. Never tried in co-op.[/]

                You will surely run into bugs. Report them in the Bugs tab or in the comments, saying what you were doing when it happened and where.

                YOUR SAVE IS NOT TOUCHED

                The mod only acts while you play: nothing is written to your save.
