If you don’t want to use the landscape native spline spawner for a road network, or want to spawn something else instead. Here is a simple way to achieve that with multiple lanes. The mesh in question is a 4mx4m simple plate so we are not using the Y bounds at all, but you can create a new MeshY variable and use that as the multiplier in the second ForLoop node instead. this way you can use rectangle shaped meshes and still get acceptable results.
