We are currently developing a VR application with the Cesium plugin for Unreal Engine (UE 5.3.2). The basic idea is to switch between a miniature map on a table and a map with a 1:1 scale (similar to Scaling and georeferencing?). We have separate levels for both modes right now and switch to the 1:1 level by placing an actor with a global anchor on the map table.
However, we have issues with the actor’s latitude and longitude. We currently scale the miniature map using a CesiumGeoreference with a scale of 0.14. If we use a scale of 100, we get the correct real-world coordinates at the actor’s location (i.e., latitude and longitude for the global anchor). If we reduce the scale, we get incorrect values for lat/long at that location. The smaller the scale, the bigger the error.
We test it right now by placing a sphere with a global anchor component on the map at a position with known real-world coordinates. We then change the map’s scale and check the actor’s position. The sphere gradually moves away from the initial position on the map (actor’s lat/long stay the same) and glides under the map.
@janine@tiuri I’ve found that selecting the globe anchor component and then changing the value of either:
Adjust Orientation for Globe when Moving
Teleport when Updating Transform
Results in expected behaviour. Oddly enough if you then change it back to the original value (by ticking the box, not undoing) then the expected behaviour remains. Undoing the change via Ctrl-Z then results in the incorrect behaviour as described in the original post.
Unsure what causes originally causes this to be required though.
