CityGen is an Unreal Engine 5 plugin for building indie city-builder, RTS, and 4X games on top of infinite procedural worlds. It's built on WorldGen — inheriting its chunk streaming, biomes, hydraulic erosion, and foliage systems — and adds the city-builder layer on top: the tools the player uses to actively shape their world. Roads, building placement, and zone systems, all running in real time with no baked landscapes or pre-authored heightmaps.
In the last video the player could draw bridges over valleys with pillars underneath. In this video the player can finally *keep* what they built — quicksave / quickload of the entire road network plus terrain deformation, undo on the last clicked road point, and a demolish mode that removes roads with a single click and re-flattens the terrain. The editing loop is closed.
