Is there way to avoid unwanted physics collision with landscape border edges?

hi i am making physics racing game, everything works very nice… but i cant resolve unwanted collision hit of physics sliding object on landscape when it is passing border edges which launch up my wheels ? is there any solution ? I have found on forums, simillar problem… and bulletphysics solved this by some “INTERNALEDGESDetection”… there is maybe some little vertex offset due to collision meshes for landscape are not welded at that area. THX.

Same problem is with splineMeshes, where meshes array along spline are also not welded togethere vertex by vertex… I did procedural ultrasmooth roadmesh with blueprint where whole road is one merged mesh and no collision can appear there. I have also setup “MIN TRIANGLE AREA in physics settings to 10 which helped a bit”

There is way to do that by making raycast driven wehicle but I would like to use that standard physx shape collision.
