At some point, you will want to merge certain scenes or projects together. As long as you can navigate to the folder you saved it in, it's very easy to do. Just simply right click and "Load Level" and select the .tnz scene you wish to merge or add to a project. Then simply render as you normally would or send to a renderfarm if that's something you're into. My PC can handle rendering and I only make small projects so it's never been an issue for me personally. Just make sure to fully utilize the Sub-xhseet folder system and you could very easily have a neat and well polished project with a few simple clicks.
