Engine doesn't support Windows OS yet. Sorry...
Engine might not work on Windows OS!
Simply open the engine and terminal window will ask you to input path to .OBJ file you want to render, simply type in the path to your file and let engine render it for you. You can also use some prefabs in 'assets' folder.
