Title: **Node reference - Perlin noise**

The nodereference says:

*Scale: The scale setting controls the overall scale of the noise pattern generated. Increasing the scale value makes pattern larger overall*

You should mention that the scale input is a vector which is useful for stretching the noise.

But use with care, all 3 components must be non zero.

If a scalar is used, the converted vector seems to be divided by sqrt(3), since dividing the input vector by a constant,

or using the same constant as scale input, gives the same output.

Noted. The node reference is due for some major expansion in the future.
