I am having a hard time finding a Distorted Perlin macro and I like to know where can I find one?
How about the built in Phase Distortion option in the Perlin node? Edit a Perlin node and turn on the “Enable distortion input” check box. Once you do this the “Phase Distortion” sliders will become available, and once you click the OK button the node will now have an additional input (on the left side of the node) to hook up a height field.
From the WM docs:
[b]Enable Distortion Input:[/b] When checked, an optional input is revealed on the Perlin Noise device that accepts a heightfield. The distortion input allows you to shift the coordinates that are fed into the Perlin Noise device in a certain direction; this allows some very interesting effects to be created.Phase Distortion Strength: The amount that the noise function should be shifted in a given direction. This controls the strength of the effect; low values provide only a subtle effect, while large values can be quite dramatic and wild depending on the heightfields.
Phase Distortion Direction: The direction in which the coordinates should be shifted. Specified by an angle, where 0 is to the left, 90 is down, 180 is to the right, and so on.
The macro was done for v0.99, and if you look inside the macro, it does exactly what marmil said. In fact it does even less, because the macro doesn’t let you specify the Distorsion Input nor some other parameters…
Anyway, you can find it here :
