DBDToolbox is an application that can extract assets from the game Dead by Daylight.
It might also works for other games.
The recent PTB (5.7.0) is currently unsupported because of the Unreal Engine update (from 4.25 to 4.27).
This is a known issue and I will try to fix it in my free time.
You can download the latest version at here: DBDToolbox.zip
