I developed a Lidar that uses a bunch of LineTraceByChannel to measure distance to the Landscape and objects in my map. It’s worked fine in UE4, but since upgrading to UE5, some of the line traces pass through the landscape and instead detect an object underneath (if one exists).
It seems to consistently happen at certain spots in the Landscape that correspond to edges, but I haven’t tested every location.
Here’s a simplified test with one such location:
Is this a known bug, or is there something badly defined in my landscape?
