I am having crashes on startup, run out of RAM
Change your JVM arguments to this:
-XX:+UseG1GC -Xmx<MaxRAM>G -Xms<MinimumRAM>G -Dsun.rmi.dgc.server.gcInterval=2147483646 -XX:+UnlockExperimentalVMOptions -XX:G1NewSizePercent=20 -XX:G1ReservePercent=20 -XX:MaxGCPauseMillis=50 -XX:G1HeapRegionSize=32M
Change the <MaxRAM> and <MinimumRAM> to what you can spare, try to reach the stars.

Is there a Multiplayer server for this project?
There is no server. The Cubic Chunks mod can barely handle 40 players on a server, let alone 100 or more, because of its rendering limitations. Once approved you'll build your own section in your own single-player world, then we'll merge everything together over time. This was clearly stated in the original video.

However, (relatively) small groups of people can work together in Build Teams that have their own independent servers, and will collectively submit their server world file when they are done.

Roads don't show up
Make sure you have Generate Structures: On when you create your world. You can also check if OpenStreetMap has the road you are looking for marked down (Terra uses OSM data). If it does, make sure you teleported properly (/tpll <lat> <long>),  and if that is not the case, follow the instructions in the file on Terra 1-to-1's Github. 

How can I get a city's coordinates?/How do I teleport to a specific place?
Using Google Maps or OpenStreetMap, find the location you want and right-click on it. On Google Maps use "What's here?", and on OpenStreetMap use "Show Address". It will give you the coordinates in a decimal lat-long form with a comma in the middle, copy and paste it into the /tpll command in-game.

Install 64-bit Java for users with mismatching architectures
Go to, and choose a 64-bit installer.
In your launcher change your JVM of choice to the 64-bit one you just installed.

Why am I spawning on a mushroom island?
You're in the right place! The world spawn is on this mushroom island. To go to your city, type /tpll <latitude> <longitude> with the coordinates of your city.

What does this mean?

It means you should dedicate more RAM. Look at Question 3 for more information.

How do I know if someone is building in my city?
You can look at the map on this website. However, just because someone else is already building there, that does not mean that there is no space for you. Most cities are big enough to accommodate multiple builders working independently, as long as they do not build in areas that they have not been allocated through this website. You can also form a Build Team with other players and work together on a server.

Can I use a mod that creates all the buildings from an API?
Right now we want to maximize artistry as much as possible. Automatically building the buildings kind of defeats the purpose of the project. We are starting to use it for large complex areas like manhattan.  For now, only use it if necessary, or to create the shells of buildings.

What about memorable buildings no longer there, like the World Trade Center and so on?
Not in the project. All builds should reflect their current state as seen in the world.

Are unofficial/cracked versions of the game admitted into this project?
No, we in no way endorse, condone or encourage people to use cracked, illegal or pirated versions of the game, or any software that is obtained in any manner not authorized by the legal copyright owners. If you would like to participate in this project, you can buy a legal version of the game here: Buy Minecraft
