This is an UNOFFICIAL port of the well known create train track mod. The original mod was made by littlechasiu. Sadly the mod hasnt been updated in years so i am now updating the mod to the newer versions of minecraft, i will also try to expand on some features that i think are missing and are usefull.
The mod requires (ofcourse) the create mod. When the world is running you can go to http://localhost:3876/ in your browser and there it is. You will then see your map live where all tracks and trains are.
If its a multiplayer server you will have to type in http://[your computer's IPV4 address]:3876/ (ONLY people on the same network). If people outside your network want to see the map then search http://[your public IPV4 address]:3876/
If its a hosting site where the server is located then its [your server address]:3876/, do note that the server provider needs to support extra port forwarding.
For the more detailed explenation, go to https://modrinth.com/mod/create-track-map all ins and outs are already explained there.
