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.
Last video the player could draw roads and the terrain reshaped itself around them. This video the player can put a road OVER terrain — bridges over valleys and rivers, with pillars underneath, and a different mesh on the bridge span itself. Plus a pile of road-tool polish: continuous joins, self-intersection junctions, Cities-Skylines-style fixed-angle bends, filleted corners, slope-aware drops.

✔ Bridges — road above terrain leaves the ground untouched
✔ Hysteresis — bridge spans don't flicker on uneven ground
✔ Pillars — dual ISMs underneath, scaled to fit the gap
✔ Bridge mesh swap — different road mesh on bridge spans
✔ Continuous join — extend, bridge between, close into a loop
✔ Self-intersection junctions — figure-8 roads get auto plazas
✔ Fixed-angle snap — Cities-Skylines-style increment + max bend
✔ Filleted corners — arc-matching Hermite tiles, no kinks
✔ Slope-aware drop — bridge ramps stay at the spline Z
