landscape Landscape + trace + displacement = problem

[vadim.lisev]

Hello. I test "wheel_traces.world" from Art Samples demo. I have issue with height scale of terrain detail material and trace. When I increase height scale I get strange effect (like vertex intersections). How do i can avoid this?

Hello Vadim,

the effect that you observe is absolutely normal, the fact is the displacement in this case extends against geometry normals.

Please note that by default our artists set the value to 0.246, which allows to achieve the desired visual result. Increasing height scale much more gives you result where geometry peaks begin to intersect with each other, keep pushing above the scale value and you will see how the curves are deformed even more.

Here is raw example how it works:

Long story short - expected behavior for this case, definitely not a bug.

Thanks!
