I've used skylines of New York for IBL in the past with no problem. In this case, I just quickly made a fake skyline because this is future NYC. But the skyline is so magnified that it's pixelated. I tried everything. Scale seems to be ignored, both in the Visual tab, and in the sky settings tab. I've even sized down the image to no avail. I think I'm going to just have to give up and stick some skyscraper objects outside the window.
