If you are asking if you can send out an interactive walkthough to a client as a single package and do the walkthough without the Editor, then Yes. Once you’ve done the packing or cooking, all the code necessary for the rendering and interaction will be packed into a executable, any resources (images, models…) will be packed into package files. YOu only need to distribute the final exe and associated package files for the client. No edit is needed from then on. Its just like a video game. You wont need the editor to play the game.
