C4D Octane User Documentation

The Noise 4D node mimics the Cinema 4D Noise shaders, using OSL versions of these noises. Use Noise 4D instead of the actual Cinema 4D noise shaders, which are not supported in Octane. For speed and reliability, the Octane Noise node, discussed here, is the better first choice, though with less noise options available. 

How to Use

Open the Node editor and prepare the setup as you see in the image below. Any "Texture", "Power" or "Amount" channels you can use the Noise texture in those channels (as the Float texture).

Noise Texture Settings

Noise

There are 31 different noise types. See the menu.

In the image below you can see four of the available 31 noises in the Noise 4D Texture.

Power

A multiplier which controls the overall brightness of the texture.

Octaves

Sets the scale of the detail in the noise.

Lacunarity

Determines the amount of additional detail for every octave.

Gain

This value will make the noise brighter or darker.

Global Scale

Sets the overall size of the noise, expressed as a single percentage (meaning the value is uniform for all axes).

Relative Scale

Expressed as three percentage values, one for each axis, allowing for independent scaling of the noise.

Add Transform

Sets the position, scale, and rotation of the texture on the surface, as explained here. 

Add Projection

Sets the way the texture is projected onto the surface, as explained in this section.

Time

This value sets the state of the noise by time. To animate the effect, you will need to set beginning and ending time values by keyframe. 

Absolute

Sets the absolute value of the noise.

Use 4D Noise

Switches between 2D and 4D noise.

Sample Radius

The radius to use for the noise.

Seed

The seed value for a unique noise pattern.
