I'm using the ppkx from here: https://www.arcgis.com/home/item.html?id=7d4ab07ef8014be28e520e60acb14108
The example works with the sample data, however when I try to use my own data (situated in central Europe) it keeps failing in myriads of ways.
Unless I use WGS84, the sun point creation step throws an extent error no matter how large I set the extent ("default" doesn't work either, obviously). When I transform all my data into WGS84, at least the sun points are created, but that's as far as it gets. The second step fails with a "value required" error, but there is nothing left in the parameter panel to enter. The terrain isn't required (example runs with and without it).
I even tried shoving my data into the example scene, but that didn't help either. The tasks suggest they work everywhere, but do they actually only work for that specific spot?
