Basically, from what I gather by the video tutorial, is that everything that the sky_camera can see (hopefully only what is in the box with the camera, and not your playable map) is scaled up for gameplay and that actually tools/transform/scale is only going to be needed to compare the scaled stuff to whatever you create as your tiny environment, seeing as you will, or at least can, delete everything you scale down (reference objects from the main level) except, of course, the sky_camera.
So, if you really wanted to, and knew what you’re doing, you could, theoretically, go into your map, make a hollowed box off to the side of your map, put a sky_camera in the middle of it somewhere, and set up you mini props around it, right? I mean, if you went through trial and error a few times getting the props in the right places and sizes, this would be all you needed to do.
…is there any point at which I errored in my speculation?
