Creating spline mesh in UEFN

Hi,
I wanted to create something on my map using pipes like that. Sadly all the tutorials that I have found use blueprints with spline. This doesn’t seem to be working in UEFN.
Is there any other way to achive same effect inside UEFN or should I just create my models in Blendrer and import them?

Hello,

I didn’t implement this myself, but I was on a game jam project where someone used the Landscape systems splines to make mesh tunnels.
