Line trace is not hitting spline mesh?

Hi!

So I’m in the middle of a small “Wipeout-like” game project.
The problem is that the line trace I use to make my vehicle hover at a certain distance from the ground is not hitting the spline mesh I use as a road.
It works on terrain and other actors, but the spline actor is invisible to the line trace.

If you have any idea, please help me out!
Thanks!

After a loooong night of searching, I finally found the solution!

The problem wasn’t in the mesh collision details, but in the “Add Spline Mesh Component” node of my blueprint: I wasn’t aware but there’s a WHOLE detail panel when you select that node, and the collision presets are set on “no collision” by default.
