Octane for Houdini

The Marble procedural node is similar to the Turbulence texture, but it's fine-tuned to create marble-like noise patterns (figure 1).

Marble Parameters

Power - Controls the texture's overall brightness.

Offset - Sets the texture position in 3D space.

Octaves - Adjusts the scale of detail in the noise.

Omega - Controls detail in the underlying fractal pattern.

Variance - Randomizes the Marble pattern.

Transform Pin - Positions, scales, and rotates the surface texture.

Projection Pin - Sets how the texture projects onto the surface.
