It should, unless it somehow gets changed mid-scene.

Noise Generators
There are three noise generators implemented. Changing the noise_generator will
change the appearance of noise based patterns, like bozo and granite.

noise_generator 1 the noise that was used in POV_Ray 3.1
noise_generator 2 range corrected version of the old noise, it does not show the
plateaus seen with noise_generator 1
noise_generator 3 generates Perlin noise
The default is noise_generator 2

Note: The noise_generator can also be set in global_settings

Noise_generator
There are three noise generators implemented.

noise_generator 1 the noise that was used in POV_Ray 3.1
noise_generator 2 'range corrected' version of the old noise, it does not show
the plateaus seen with noise_generator 1
noise_generator 3 generates Perlin noise
The default is noise_generator 2

Note: The noise_generators can also be used within the pigment/normal/etc.
statement.
