using UE5.7: created with wizard google maps tile set. set cesium geo reference to true north (geocentric) the sun rises in the south and sets in the north. tried to find a way to fixed it. no luck.

Hi @Tamir_Offek , welcome to the forum! Could you outline the exact steps you took to recreate this? I tried: Add GP3DT and set georeference latitude to 90, longitude 0. This places the origin on true north I could change the month/day and timezones and it appears the sun is in the correct positio…

Hey @Tamir_Offek , This seems to be a known issue based on this github issue . I would note that we don’t recommend using true origin mode ( line 18 here ) for most use cases. What is your use case, does it require true origin? It would be useful to know so we can better advocate for the fix internal…

I would recommend working around this issue by creating a second georeference and setting the CesiumSunSky to use that georeference instead. You can then place that georeference wherever you want to treat as the center (in terms of correct sun placement) and still use the original georeference in tr…

for several reasons I need all the elements in the level to be aligned to geocentric mode (true north). does cesium aware of this bug?

I need it in order to to get two far points on the globe to use the same axis system and this system should still be correct for both points. if you are using cartographic mode (with base LLA) points that are far from the base LLA use incorrect local axis system that gets increasingly erroneous as t…
