Overview

Surface is a definition of surface type which contains material, set of meshes and other objects. Surfaces are used for painting and object creation by means of a brush.

Learn more about the surfaces from the view of the Scene Editor.

How to create

To create a new surface, it is easier to make a copy of an existing surface and change it. They are located in 'Content\Vegetation'. Also, check asset store for new surfaces.

A surface consists of groups of elements, groups, for its part, include elements. The element indicates the probability of the element getting when painting with a brush, and other settings.

Terrain

Surface is supported by the Terrain. It is the best way to make nature worlds.
