One of the more common texture map types is the Normal map. There may be some situations in which you will have height map information for your mesh, but not a normal map. Fortunately, the Shader Graph allows you to generate Normal map data from Height map data. To do this, you’ll use a Normal Create node. This node allows you to supply a black and white Height map texture to generate a Normal map. This becomes very useful when you’re trying to add additional detail to your Shader’s surface to determine how it should interact with the light and how it should appear to the viewer.
