Hey there, Jon. Nice work so far! It looks like you’re checking out an old tutorial for mesh generation. Things have changed since the release of 1.4. Everything is controlled by the AbstractMap.cs script now.

Check out the DataExplorer example in the SDK. You’ll likely want to configure a road vector layer with a collider for your use case. You see more about how to set this up here: https://www.mapbox.com/unity-sdk/overview/data-explorer/#roads
