::*'''Frequency''' Use the slider and/or the number field to alter the complexity or coarseness of the noise pattern. The higher the number, the more noisy and mottled the effect will be.

The higher the number, the more noisy and mottled the effect will be. Affects the noise brush and is taken into account via automated noise generation. Range: 1-10000 | ||
::*'''Amplitude''' Use the slider and/or the number field to alter the maximum height range (black<->white) of the noise pattern. The greater the amplitude, the greater the contrast between the darkest (lowest) and brightest (highest) portions of the noise pattern. Affects the noise brush and is taken into account via | ::*'''Amplitude''' Use the slider and/or the number field to alter the maximum height range (black<->white) of the noise pattern. The greater the amplitude, the greater the contrast between the darkest (lowest) and brightest (highest) portions of the noise pattern. Affects the noise brush and is taken into account via automated noise generation. Range: 1-32000 | ||
::*'''Base Offset''' Use the slider and/or the number field to set a clamp value, in [[exterior cells|units]], for which the noise pattern is started from. The higher the value, the higher the elevation for which the noise pattern will generate. Affects only | ::*'''Base Offset''' Use the slider and/or the number field to set a clamp value, in [[exterior cells|units]], for which the noise pattern is started from. The higher the value, the higher the elevation for which the noise pattern will generate. Affects only automated noise generation. Range: 1-32000 | ||
::*'''New Seed''' Press the New Seed button to manually generate a new seeded value for the current noise function. The seed numbers are used to recall a particular set of results for the various characteristics that make up a randomly generated noise pattern. Use the neighboring number field to manually cut, copy, paste or enter in seed numbers. Range: 0 to ∞ | ::*'''New Seed''' Press the New Seed button to manually generate a new seeded value for the current noise function. The seed numbers are used to recall a particular set of results for the various characteristics that make up a randomly generated noise pattern. Use the neighboring number field to manually cut, copy, paste or enter in seed numbers. Range: 0 to ∞ | ||
::*'''Additive''' Use this checkbox to ensure that | ::*'''Additive''' Use this checkbox to ensure that automatically generated noise will only be ''added'' to, or ''raise'' the current heightmap pixels. Note that it is possible to have both the Additive and Subtractive checkboxes enabled at the same time. In this case, noise will be generated that can both raise and lower the heightmap pixels. | ||
::*'''Subtractive''' Use this checkbox to ensure that | ::*'''Subtractive''' Use this checkbox to ensure that automatically generated noise will only be ''subtracted'' from, or ''lower'' the current heightmap pixels. Note that it is possible to have both the Additive and Subtractive checkboxes enabled at the same time. In this case, noise will be generated that can both raise and lower the heightmap pixels. | ||

::*'''Persistence''' Use the slider and/or the number field to specify how the frequency value is modulated by the amplitude per each octave. Higher numbers usually equate to a noisier pattern. Affects only the noise brush. Range: 0-100 | ::*'''Persistence''' Use the slider and/or the number field to specify how the frequency value is modulated by the amplitude per each octave. Higher numbers usually equate to a noisier pattern. Affects only the noise brush. Range: 0-100 | ||
::*'''Octaves''' This is the number of successive noise function passes involved in final noise generation. The higher the number, the more passes, or layers are involved in the noise generation and the more complex the patter will appear. Affects only the noise brush. Range: 0 to ∞ | ::*'''Octaves''' This is the number of successive noise function passes involved in final noise generation. The higher the number, the more passes, or layers are involved in the noise generation and the more complex the patter will appear. Affects only the noise brush. Range: 0 to ∞ | ||
::*'''Generate!''' Use this button to | ::*'''Generate!''' Use this button to automatically generate a noise pass onto the currently selected heightmap section. This button will take into account the frequency, amplitude, base offset, additive, subtractive, seed# and random seed parameters and flags. The area of generation can also be further controlled by the lasso and marquee selection tools. | ||
