Gravel

Reference
Index

    GRAVEL looks like a mix of large and small stones.

How Does It Work?

    This is a fractal algorithm, so it has all of the typical fractal parameters (Roughness, Lacunarity, and Lacunarity Lock).

    As the Rock Height parameter is increased, the smaller gravel pieces will become more pronounced and will start appearing on top of the larger gravel pieces.

    The Gap Size parameter changes the space between gravel pieces.  Since smaller pieces are more likely to appear in the gaps of the larger gravel pieces, increasing the gap size allows more small gravel to appear.  Increasing the gap size also reveals more of the Background.

Hints!

    Try using low Lacunarity settings and a Small Gap size to get a scaly reptile like skin. Large Gap sizes can be used to get a spatter type texture.

Common Parameters

 

 

 

 

Input Seed

The seed for the random number generator that is used to create the texture.

 

 

Roughness

The roughness or detail level of the pattern.

 

 

Lacunarity

The relative scale of the fractal layers of clouds.

 

 

 

 

Lacunarity Lock

When enabled, locks the size of the top fractal layer while adjusting Lacunarity.

 

 

 

 

Rock Height

The height of the smaller rocks compared to the large rocks.

 

 

Gap Size

The size of the gap between rocks.

 

 

Brightness

The brightness level of the pattern. Higher values move the color toward Rocks.

 

 

Contrast

The contrast or sharpness between the Background and Rocks.

 

Strata Function

Blending control applied the the fractal layers of the pattern.

 

Blend Function

Blending control between Background and Rocks.

Color Component Parameters

 

 

Background

The background color value.

 

Rocks

The rock color value.

Percent Component Parameters

 

 

Background

The background percent value.

 

Rocks

The rock percent value.

Bump Component Parameters

 

 

Background

The background bump elevation.

 

Rocks

The rock bump elevation.

 

 

Bump Scale

A scaling factor for the bump values.
