    • Project mention: So...apparently the hoarder bug model has organs inside of it? | /r/lethalcompany | 2023-12-06

    I used a tool I found on Github called AssetRipper. All you gotta do is open the program and select the game folder. You also wanna download Unity 2022 to browse through the assets since they‘re stored in a Unity specific format (.asset). I don‘t know the specifics of turning it into a useable format like fbx but there should be plenty of tutorials on that.
