Landscape Combinator is an Unreal Engine 5.8 plugin for Windows and Linux that lets you create landscapes from real-world data in a few simple steps:

• Create landscapes from real-world heightmaps (with a basic landscape material to visualize them),
• Create landscape splines from OSM data for roads, rivers, etc.
• Automatically generate buildings using splines representing buildings outlines in OSM,
• Add procedural foliage (such as forests) based on OSM data.

When creating a landscape for a real-world location, the plugin will adjust its position and scale correctly in a planar world. You can thus create several real-world landscapes of various resolution and have them placed and scaled correctly with respect to one another. The plugin also has a blending feature to modify the landscapes heightmap data to make the transition between different landscapes as seamless as possible.

For more information, please refer to the documentation.
