Would you be able to provide the ifsjson file? I'll investigate

Oops, no need for the save file, managed to reproduce. I think I can fix it this weekend and then release a patch with the other projection related fixes 👍

I've managed to solve this issue, see details in this commit 420a402
Drawback is that it'll take a bit more times to clear up noise at the poles, but at least it will be correct. Also I checked the results in Blender: image This will be in the next release.
