dose the cesium for unreal support the cartesian coordinate system？？？
and how to use it？
Hello @mr_orange ,
We use a cartesian coordinates system called Earth-Centered, Earth-Fixed (ECEF). The default CesiumGeoreference keeps track of how the Unreal world coordinates sit in terms of ECEF. To convert from Unreal coordinates to ECEF or vice-versa use the conversion functions found on the default CesiumGeoreference actor.
