World Normal Node
Per pixel calculation of a vector that represents the surface normal in world space. A normal vector is a unit vector perpendicular to the surface that points to where surface is faced. This data is very useful and common for lighting calculation. This node also allows to receive a normal vector in tangent space to shift the normals around. The most common use case would be to use a normal map texture in tangent space to perturb the object's surface normals.
NOTE: Do not confuse with Vertex Normal node.
