The original “project” in BotW took a while to accomplish, especially since I also wanted to find out what time of the day the pictures were taken (so the shadows would be identical), and I did it more or less blind so finding the right spot wasn’t always easy either (I had the most trouble with the Eldin Canyon and Nameless Forest pictures). Took a good month of trial and error back then.
Since the locations haven’t changed between games, the “requirement” to get the weather AND time right no longer applies, and the fact that I know the BotW map by heart after playing basically nothing else for 6 years straight, the TotK version was a lot easier. Took me about a week, including the video version ;)
Maybe Hyrule is a Discworld-esque flat map that rotates every couple of years and they’re now in the phase where the “map” is rotated by 180 degrees? =P
…joke aside, I’ve heard three theories about this that make a bit of sense:
None of these are in any way confirmed tho - they’re just fan theories.
