Adds random noise to the appearance of a material. Noise randomly alters pixel-level UV mapping by applying a fractal noise function.
Noise patterns can be very complex and are a versatile way to create apparently random patterns. They are also good for simulating surfaces found in nature, as is characteristic of fractal images.
Noise parameters interact closely with each other. Slight variations in each can create noticeably different effects.

To add noise to a material:
To remove noise from a material:
Noise is no longer applied to the map.
To animate the noise effect:
By default, 3ds Max sets animation keys at either end of the active frame range.
These controls appear on the Noise rollout for many 2D maps:
Determines whether the Noise parameters affect the map.
Sets the strength of the fractal function, expressed as a percentage. If the amount is 0 there is no noise. If the amount is 100 the map becomes pure noise. Default=1.0.
Or iterations: The number of times the function is applied. The effect of the level is dependent on the Amount value. The stronger the amount, the greater the effect of increasing the Levels value. Range=1 to 10; Default=1.
Sets the scale of the noise function relative to geometry. At very small values, the noise effect becomes white noise. At large values, the scale can exceed the scale of the geometry, in which case it has little or no effect. Range=0.001 to 100; Default=1.0.
Determines whether animation is on the noise effect. This parameter must be turned on if you intend to animate the noise.
Controls the speed of the animation of the noise function.
