|Function||Generates a Perlin noise|
|Nearest C4D equivalent||Noise shader|
This node produces a Perlin noise (see the Musgrave node for other noise types). By default this node produces an uninspiring, low-contrast coloured texture but manipulation of this with other nodes produces very good results.
Note: a * symbol next to the name indicates the parameter also has an input port. A # symbol indicates that the parameter can only be changed with an input node, not in the node itself.
The coordinate system to use for projecting the texture. You can link a Texture Coordinate node to this port, for example.
This changes the size of the texture, but as is common in Cycles 4D, increasing the scale increases the 'amount' of texture used, so it appears smaller on the object. The effect is the same as the Musgrave node; see that page for some examples.
Increasing this value will increase the level of detail in the noise.
This setting will distort the noise giving an increasingly wavy, curly pattern:
A monochrome colour output.
A numeric value which is the brightness of the colour. You could link this to the Fac port of a Color Ramp node to get a coloured noise, as shown in the example at the top of the page.
