Road infrastructures and Parametric Modeling inside Unity
Create unique road networks directly in Unity with both built-in customizable dynamic crossing prefabs and custom crossing prefabs based on your own imported models.
Bring your scenes alive with additional side objects: bridges, guard rails, fences, walls, power lines, tree lines or any other type of geometry following a path.
The EasyRoads3D v3 toolset can also be used to create other infrastructures such as railroads and rivers with the riverbed carved in the terrain.
– Winding roads or dirt paths in scenic environments and complex city road networks.
– Built-in customizable crossings
– Custom crossings – import your own crossing models
– Side Objects: bridges, guard rails, fences, walls, power lines, etc.
– Custom shapes for other infrastructures like railroads and rivers
– Terrains conformed to the road shape, grass / tree removal, optional road shape baking in the terrain splatmap
– Road data import for real world visualization (OSM/KML)
– Scripting API: road creation through code both in the Unity editor and at runtime
