Unreal Engine is bundled with the Epic Game Store software. You'll need to specifically install version 4.18.3 of Unreal Engine in order to mod Bloodstained.

Download: MirrorPluginToolbar v1.2

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.
