The Z-axis value of a point on a tilted model obtained from a long distance is inaccurate

[GuoYu]

I loaded a tilted model in the scene and used “Line Trace By Channel” to get the coordinates of the clicked position. When the Pawn is very close to the clicked position, the z-axis value of the coordinate is accurate, but when it is a little further away, the z-axis value of the coordinate is inaccurate, and the error is large. I have tried several tilted models and this happens all the time. Is there any way to solve this problem?

Hi @GuoYu, welcome to the community!

Your post sounds similar to another thread on the forum. Could you try the suggestion that is posted there?

Cesium terrain z values incorrect over large distance

Whilst doing a Line trace down to the Cesium terrain (on its own channel), z values seem to be inconsistent over a large area (I think I read like 1m every 100km away from the Georeference anchor or something like that). I’m a bit confused as to how to use cameras to force tilesets to load in detail to ensure these linetraces are correct, I’d prefer to not use them at all if possible as im placing them using the z values found by this line trace (as such around half are under the surface and wou…
