Marble Node

Access: Nodes > Procedural > Fractal

The Marble node is a procedural node which creates a marble-like effect on a surface.

Marble node displayed on an object in Mari.

Marble Node Inputs

Position: Samples the marble effect at the input position. Defaults to standard surface position when Space property is set to 3D and standard surface UV when Space property is set to UV.

Veins: Uses the input value as the veins.

Bleed: Uses the input value for between the veins and background.

Background: Uses the input value as the background.

Marble Node Properties

Scale text field, slider	Controls the overall scale of the effect. Scale value set to 14. Scale value set to 73.
Octaves text field, slider	Controls the density of marble effect lines on the surface. Higher values result in more densely packed lines, lower values result in sparser lines.
Frequency text field, slider	Controls the crinkling of marble effect lines on the surface. Higher values result in more crinkled lines. Frequency value set to 2.3. Frequency value set to 7.1.
Increment text field, slider	Controls the density of marble effect crinkled lines on the surface. Lower values result in more densely crinkled lines. Increment value set to 0.1. Increment value set to 1.1.
Space dropdown	You can specify whether the marble effect should use 3D space, or UV space coordinates.

Color

Veins swatch	Specify the color to be used for the marble veins. Veins color set to green. Veins color set to purple.
Bleed swatch	Specify the color to be used between the veins and background.
Bleed Amount text field, slider	Specify how much of the Bleed color should appear. A lower value shows less bleed, a higher value shows more bleed.
Background swatch	Specify the default color to be used as the background of the marble effect.
