The Noise node generates a procedural noise texture. It uses an implementation similar to Maya's. It uses two colors that can also have texture maps assigned to them.

This section describes the input sockets of the node. The sockets have dedicated parameters, which are further described below.

Mapping – Allows a UVW Mapping or a UVW Randomizer node to be connected to determine the mapping of the ramp.

Color 1 (input socket) – Controls the first of the two colors used by the Noise procedural.

Color2 (input socket) – Controls the second of the two colors used by the Noise procedural.

Threshold (input socket) – Specifies a value added to the noise function. Note that values above 1.0 are clamped.

Scale (input socket) – Controls the scale for the noise UVW coordinates.

Origin (input socket)–  Controls the translation for the noise UVW coordinates.

Implode (input socket) – Controls the amount of implode performed on the UVW coordinates.

Implode Cen (input socket) – Specifies the center of the implode effect.

Type – Specifies the type of noise to be created through the Noise procedural.

Color 1 – Controls the first of the two colors used by the Noise procedural.

Color2 – Controls the second of the two colors used by the Noise procedural.

Size – Controls the scale for the noise UVW coordinates.

Iterations – Specifies the UV noise iterations

Phase – Specifies the UV noise phase.

Low – Specifies the lowest possible value of the noise function. Values below this are clamped.

High – Specifies the highest possible value of the noise function. Values above this are clamped.
