Roads and Rivers – Building the Logic Behind a Believable Overworld

The overworld of Veildelve – A World Shaped by Aether is not meant to feel like a collection of isolated hex tiles. It should gradually form a connected and believable landscape. One important part of that is the underlying logic used for roads and rivers.

Recent development work has therefore focused on making both systems connect reliably across multiple hexes while maintaining a consistent visual appearance.

Roads need more than a line from edge to edge

Drawing a road from one edge of a hex to another is relatively simple. The challenge begins once curves, branches and different road configurations have to connect with each other.

Without additional logic, these situations can quickly create visible gaps, overlaps or unnatural transitions.

A significant part of the recent work therefore focused on road junctions and branching paths. Y-shaped junctions in particular required additional refinement so that the branching road connects convincingly into the main road.

The goal is a system in which different road elements can eventually be combined freely — straights, curves, branches and Y-junctions — without requiring manual fixes for every individual map configuration.

Rivers are sensitive to small differences

Rivers introduced a different set of challenges. Even relatively small differences in geometry can make a curved river appear much wider than a straight section.

The river system has therefore been adjusted so that straight sections, curves, crossings and branches share the same visual width.

Bridge crossings are part of this work as well. A river should maintain its natural width underneath a bridge instead of suddenly expanding or narrowing.

The same principle applies to Y-shaped river junctions. Main rivers and side branches need to merge naturally without creating an oversized body of water in the centre or leaving visible internal shoreline fragments where the two sections meet.

Hex-edge connections matter

Another important part of the system is the connection point along the edges of each hex. Roads and rivers need to reach these points consistently enough that neighbouring tiles can connect without visible offsets.

Individually, many of these details may seem minor. Across a large overworld made from many interconnected tiles, however, they strongly influence whether the landscape feels continuous or visibly assembled from separate pieces.

More than decoration

Roads and rivers are therefore more than visual decoration. They are structural parts of the world and need reliable underlying rules.

The current work establishes the foundation for assembling increasingly varied road and river layouts from reusable hex elements while keeping their appearance consistent.
