Hello, this tool is going to be updated, when needed, to the latest engine versions. I’m working on update now, and some more features are going to be added in the future.
As for your second question, you can see what you will get in the pictures and videos. Plus you can always use your own road meshes and materials, this tool has many features which will aid you in the process of building road network.
Best regards,
