Vehicle 'bouncing' when moving from one spline segment to another

I have a mesh attached to a landscape spline which has an associated simple box collision, which I am using to build a road.

When a vehicle moves from one spline segment to another at high speed it ‘bounces’ up. I have a theory that, where the two spline segments meet the collision boxes don’t line up exactly, creating a small lip. This lip acts as a barrier causing the object to hit the segment and bounce up.

How can I stop this effect?

Thanks, Patrick

I’m also stuck on this very problem!
And also my suspicion is that it has something to do with the transitions between the spline segments.

I tried all collision settings regarding the spline, but without success.
Does anyone have any idea what the reason for this jumping away from the splint at high speeds might be?

I´m also using UE 4.21.

Hey Roman,

I didn’t end up solving this issue directly - rather I used the landscape to provide a smoothed collision. https://answers.unrealengine.com/questions/33049/view.html may provide some help for you or anyone else that comes along.
