What materials are the Displacement templates suitable for? What are the special parameters?

Displacement material templates use parallax mapping to create realistic bump effects.

The only special parameter of the Displacement material template is the Height, which is usually defined by a height map that defines the bumpiness of the model.

The white color is the convex part and the black color is the concave part.

In the case of the figure below, the height map is pre-imported and used to define the terrain.
