Normal From Height Texture Sample
This material graph sample demonstrates how to convert a height value from a height texture to normals.
The Normal From Height Texture node is accountable for conversion from a heightmap to normals. So the Height texture (Texture 2D node) and the Height Value are connected to it and the Normal Tangent Space result is used for normals of the material.
Albedo, Metalness and Roughness values are obtained from the corresponding parameters.
