In my project, I use Cesium as terrain provider and my plugin is using Unreal built-in Georeferencing actor to compute Unreal location and rotation from ECEF coordinates. These actors positions are updated from external systems.
The issue I have comes when I set UE GeoReferencingSystem Actor
Origin Location to “Origin at Planet Center” and CesiumGeoreference
Origin Placement at “True origin”, (Cesium World Terrain is rotated of -90° in Z, according advices from Epic): the spawned
actors have wrong rotations, locations are OK.
I reproduced this issue in my own plugin and also while using instead DISGrill plugin.
The effect looks less visible for longitudes close to 0°.
It is ok when Cesium georeference is set to lat/lon/lat and Georeferencing actor used a projected CRS.
Did someone see something similar ?
