NEW IN R20
Since the normalization only makes sense for directional vectors, only data types for Vector2D, Vector and Vector4D are available.
Input the direction vector into the Node whose length you want to shorten to a value of 1. Note that the vector that is input must have an actual length, i.e., not 0, 0, 0. The result of the normalization will otherwise not be defined and would probably produce an error in the material.
