Cellular Noise 3D
A 3D cellular noise generator.
Parameter Types
Parameter descriptions
PositionThe 3D coordinates at which the data is read in order to map the texture onto a surface. The default is to use the current 3D object-space coordinates.
Discussion
The Cellular Noise 3D shader node procedurally generates noise patterns that you can use to add texture and variation to materials. Because this node generates noise in 3D, the texture doesn’t repeat in the Z direction, but rather continue as depth changes. Below is an example of a node graph that uses the Cellular Noise 3D node to generate a black and white pattern procedurally:

Multiply the incoming position with a constant float. The float changes the frequency of the generated noise to a higher number that corresponds with the pattern repeating more often. The output of the node runs through a Convert node to change the float output to a black and white color output. Below, the resulting texture applies to a cube:
