Hello! In this guide, I will tell you step by step how to set up a dark interface in Serious Editor 2017!
I would like to warn you that after installing the dark interface, your Editor settings will be reset to standard.

1) Download this archive - https://drive.google.com/file/d/1iWk6Ko_e9DcjOKXpmehYXr-Q89AVHdGK/view?usp=drive_link
2) Extract the "Serious Editor" folder, the "EngineGUI" file and the "Undefined" file from the archive.
3) Place the "Serious Editor" folder along the path: common\Serious Sam Fusion 2017\Content;
4) Place the EngineGUI and Undefined files along the path: common\Serious Sam Fusion 2017\UserData\Sam2017_SeriousEditor\Default;
5) Launch the editor.

Your dark interface for Serious Editor 2017 is ready! I would like to express special thanks to Asdolg for his advice on working with interface settings.
Good luck!
