The City of Titans team has sent out a brand new trailer to show off the procedural tool used to create the game. The Builder allows the dev team to automate the process of building cities within the game, "enabling in seconds what normally takes hours".
The video previews the creation of a particular section of the city of Alexandria and runs through the process of taking a map from its most basic form to Greybox to fully realized construction. According to the team, the new tool allows a streamlined method of building that allows them to "feed it parts and instructions" based on their vision. The Builder "spits out" the completed construction in a matter of minutes rather than hours / days.
You can check out the entire process in the video below, or head straight to the City of Titans site to read up on the process.
