It just happens on some locations, mostly it works. It’s not random, if it works once it always works, and if it’s going trough on some location, it always does.
The Landscape is the only object which is blocking the Terrain Trace Channel.
This bug is still under assessment by the development staff. Unfortunately, I do not have a timeframe of when a fix will be made available. I have updated the bug report to reflect that more developers are experiencing this error.
This happens on very very large chunks on Flat Landscapes Parts. The general Area where it happens in my case stays consistent but gets larger or smaller depending on the Offset on the Z Axis. Hope this information is of any help here a screenshot that showcases the Misses on a grid.
it seems not only occur on landscape, because i put a cube under the landscape, when the line trace through it(no hit occur), the line trace doesn’t hit the cube either.
But the character can be hit by the line trace.
