Normal From Height Value Sample
This material graph sample demonstrates how to convert height values to normal vectors.
The Normal From Height Value node is accountable for conversion from a height value to normals.
In this sample, a noise texture is used as a mask adjustable via the Coverage and Contrast parameters. The black-and-white mask is used as a blending coefficient for the Lerp node that performs linear interpolation between two normal maps and as the source height for the Normal From Height Value node converting the mask to a normal map.
Finally, the result of two blended normal maps is added as the Detail Normal to the edge normals via the Reorient Normal Blend node and the resulting tangent-space normal vector is passed to the material.
The Albedo color is obtained from the corresponding parameter.
