Ball jumps on colliders edges

[Dmitrii_Dzh]

I'd like to add that the edge-jump-issue is a generic Unity physics issue. The same thing happens if you use the default cubes and align them perfectly. You can tweak various physics settings to reduce the issue somewhat, but its impossible to eliminate it completely. The only collider that seem to cope with the issue is the wheel collider.

Thanks for your helpful feedback

Yes, it's not to Curve plugin-specific issue, but Unity in general — Totally agree on this one.
Just hoping that tool has the solution on how to deal with it.

I have selected the Combined option but looks like nothing really changed, the track is still generated as several objects/colliders. What I am doing wrongly?
