The Iray+ Perlin Noise map generates a pseudo-random pattern consisting of waves across the map. It is computed over several octaves which are added together for the final result. It has many uses but primarily it is used for generating procedural textures, shapes, terrain height maps and as the basis for texture effects.
The noise blends between these two colors. These parameters will have no effect if connected to a Normal/Bump parameter.

This modifies the pattern with a marble appearance. Can be used in combination with Apply Dent and Absolute Noise for more complex effects.

Intensifies the contrast between the colors but the pattern will stay the same. Can be used in combination with Apply Marble and Absolute Noise for more complex effects.

This can be used as a time control, in conjunction with 3ds Max key frames to simulate progression of the noise over time.
