The issue is easy to recreate, in a fresh Topdown project, setting the spring arm to a longer distance such as 1200 and switching the mesh floor for a landscape will make the player’s movement stutter, the stutter happens because the character is constantly turning to walk toward the 0,0,0 location, by holding the walk mouse button down the character will twitch fighting between two locations

Here’s me holding the mouse to walk in a circle while the character is constantly fighting to walk toward 0,0,0, once i let go, he moves there

fresh top down project, setting the spring arm length to 1500, camera fov to 60 and switching the floor for a landscape

Some other observations, still happens without a spring arm if camera is far enough, doesn’t happen on orthographic mode

Hi KhenaB,

Does this occur with landscapes that have been sculpted or with other landscapes as well? We have a bug report for flat landscapes that return false values on flat landscapes and this may be related.

Indeed, slightly sculpting the landscape fixes the issue

Thanks

If adding any sculpting fixed the error, this is definitely related to the trace bug, which is in our system as UE-16432. I am going to update the bug report to reflect that you are experiencing this as well.

I had the same problem with the character moving to 0,0,0 occasionally. The get cursor hit result under mouse cursor would return 0,0,0 often. As soon as I sculpted the terrain, the problem went away. I have version 4.9.2 installed.
