Used For: 3D Modelling
Download: MirrorPluginToolbar for Unreal 4.22

This is an Unreal Engine plugin that generates a “mirror table” for 3D character models. This is necessary for modifying characters and enemy 3D models in the game that flip left/right (almost ALL of them), in order for the animation to not break.

Download: QuickBMS

The first step to any mod of the game is to extract the game's pak file into a directory of uasset files so you can replace the uasset files individually. The QuickBMS software does this.
