Landscape splines lighting channels

I’m placing a path onto a landscape using the assets from the LandscapeMountains demo available from Epic for learning. I’m using lighting channels in my setup. The path using the spline, however, has no option for enabling lighting channels. Is there a workaround? Any help is appreciated.
Thank you.

Got same problem. Solved that way - u can switch lighting channels on your own landscape. And for material of roads just use Deferred Decal with Color,Normal,Roughness Blend Mode.
