The Terrain Editor is used to create and modify Terrain object of the current level. With the various Brushes it is possible to create valleys, mountains and so on. This tool also packs the Terrain Painter which is used to assign terrain’s textures and materials, changing the look and feel of a given surface (e.g. asphalt, dirt, gravel, mud, etc.).

Terrain Editing & Sculpting
The Sculpt Modes allows to edit the terrain heightmap in real-time. Once a mode is selected, simply click on the terrain to sculpt the terrain accordingly. The red circle indicates your brush size.

Advanced Sculpt Modes
These modes offers unique functionality that can be helpful in certain situations:
Terrain Painter & Ground models
This brush mode is used to paint the terrain surfaces with different textures and materials.
The Terrain Painter window will display all the available Materials that are available in the current level. Once a material is selected, click on the terrain to paint it in real time.
Double-click a material to access the Terrain Material Editor, from where to edit the existing materials and create new ones.

Ground models
The name of each material is not casual, but matches a ground model. This determines the surface’s physics (e.g. asphalt, beach sand, ice, etc.)
The full list of available ground models can be found in: BeamNG.drive\gameengine.zip\art\groundmodels.json
The groundmodels.json
file defines the physics of all the surfaces in the game.
To assign a specific ground model to a terrain material, simply name the latter with either the main Name or one of the Aliases of the ground model
In the above example, ASPHALT_WET
is the main name of the ground model, while asphalt_wet2
and asphalt_wet3
are aliases. If the terrain material is named with any of them, surfaces painted with it will have the ASPHALT_WET
surface’s physics.
