Select the outfit(s) you want to modify from the right Outfits list.
Check-off the new model for the outfit(s) on the left Model Mapping list.

Upgrade values are the increased capacity that the upgrade provides, not the absolute value.
Values can be changed by entering a new number in the grid.
The multipler buttons will apply a multiplier to all selected upgrades.

Unlike upgrade ammo is the absolute value that Aloy can carry. Ammo upgrade 0 is the default amount of ammo Aloy can carry before any upgrades. Values can be changed by entering a new number in the grid.
The multipler buttons will apply a multiplier to all selected upgrades.

Misc plugin contains items that don't belong anywhere else. The options are self explanitory.

Select the npc(s) you want to modify from the right NPC list.
Check-off the new model for the npc(s) on the left Model Mapping list.
Use the filter in the top right to see all character options

Status and errors are displayed in the bottom left. There isn't a lot of validation if things break restart the program.
Not all outfit/character swaps have been tested. If the game doesn't load or Aloy looks the same the swap didn't work.
If the game won't load or the app won't load try deleting the patch file. The patch is placed in %GameDir%\Packed_DX12\Patch_AloysAdjustments.bin.
If you change the bin file name or move it, be sure to update config.json with the new name, otherwise the program can't get the original game files.
