is there a spline based decal?

I want to make like a dirt path, but project it like a decal. A spline would be ideal for this, I cant seem to find any examples though. Does a feature like this exist, is it planned?

I’m also interested in such feature, any plans to add it ?

Unreal Engine 4 does not have this feature. It should though, because game engines like Cryengine and Torque 3D have this.
