NavMesh generation on a Spline Mesh Component surface

Hello everyone. I made a walls and stairs at runtime using spline mesh component, but NavMesh isn’t generating on a surface of the Spline Mesh components, Is there a way to make it happen? Or maybe, I should convert Spline mesh component to a Static Mesh component, but I cannot find any information on how to do either. Could you guys help me out please?

Yes, it is exactly what I am using. I’ve set the NavMesh to be fully dynamic.

Are you using this:

Sorry, no clue - was hoping for a moment that was just it.

Is there maybe a way to convert spline static mesh component to a static mesh component at runtime? I can’t find it anywhere online. :frowning:
