Quote - I also might note, but I'm not sure if this has to do with my problem or not, that the scene was set, in Reality, to be saved to "C:" something as one of those mesh light files. I'm on a Mac, and so Reality pointed out to me that "C:" etc. does not exist. I changed the location back to /Users/mydirectory/ etc.

Well, maybe that's another issue. It was easily taken care of, but could it possible account for the postage stamp sized render?

Yes, the output path is also saved to the 'light scene' I created. With a freshly started DS, then first opening your own scene, then merging one of my lights it should keep 'your' path though.

Now you are on a Mac. I have no clue if DS on Mac behaves differently from Windows. Both problems should be solved by manually adjusting path and render size, but I must agree that is a pain in the ..uhm.. 'bum' to have to do that every time..
