Here you can select from various patterns that are all generated mathematically, which means that they have no fixed resolution. In addition, the calculation can be affected by modifying settings and can even be animated. The available patterns are identical to those of the Noise Material Node and the Noiseshader in the standard Material System.
This Node creates a grayscale noise pattern by default. If the RGB option is enabled, random colors will instead be generated.
This setting can be used to define the level of detail for the Noise structure. Larger values will create more variation in the pattern and smaller values will result in correspondingly more loss of contrast and details, as well as to a blurring of the structure.
This is a numeric value on which the calculation of the pattern will be based. By changing this value, a new variation of the selected pattern will be created.
This setting is available for several Noise types and is used to define the density of detail in the gaps between fractals. Generally speaking, the density of information between the structures will decrease correspondingly with decreasing values.
This setting can be used for several Noise types to smooth the transition between brightness and the structure. Larger Gain values will produce blurring and a loss of individual details.
This setting can be used to scale the Noise structure in the U, V and W directions.
The selected Noise structures can also be modified fluidly over a span of time. Use this value to define how fast these modifications to the structure should occur.
When the pattern is calculated, positive and negative values are ascertained by default and converted to brightness values. This setting can be used to define if only positive values should be used, which results in an inversion of the previously negative regions of the structure. This will cause a brightening within the previously dark regions of the structure.
This value is available for the Noise types Displaced Voronoi, Voronoi 1, Voronoi 2 and Voronoi 3 and affects in particular the contrast within the Voronoi structure.
The Contrast is defined by the difference between the most saturated or brightest colors and the least saturated or darkest colors. If the Contrast value is reduced to a minimum, all input colors will appear in a neutral gray. Values exceeding 0% will strengthen all saturations and widen the differences in brightness further relative to a neutral gray tone.
Low Clip [-∞00..+∞00%]
High Clip [-∞00..+∞00%]
These settings are used to affect the brightness bandwidth generated in the pattern. Increasing the Low Clip value will darken all areas with low brightness further. Reducing the High Clip value will brighten all structures with low brightness further. Switching the slider positions for Low Clip and High Clip can be done to invert the brightness that is generated.
