S_TextureNoiseEmboss Creates an abstract texture by applying a EmbossShiny effect to a procedurally generated noise texture. Adjust the Light Dir to illuminate the pattern from different angles. In the Sapphire Render effects submenu. Inputs: Background:  Optional.   The clip to combine the texture image with. This may be ignored if the Combine option is set to Texture Only.

Parameters:

Frequency:   Default: 2,  Range: 0.1 or greater.
The spatial frequency of the texture. Increase to zoom out, decrease to zoom in.

Frequency Rel X:   Default: 1.5,  Range: 0.01 or greater.
The relative horizontal frequency of the texture. Increase to stretch it vertically or decrease to stretch it horizontally.

Octaves:   Integer,  Default: 5,  Range: 1 to 10.
The number of summed layers of noise. Each octave is twice the frequency and half the amplitude of the previous. A single octave gives a smooth texture. Adding octaves makes the result approach a fractal (1/f) noise texture.

Seed:   Default: 0.23,  Range: 0 or greater.
Used to initialize the random number generator. The actual seed value is not significant, but different seeds give different results and the same value should give a repeatable result.

Bumps Scale:   Default: 2.5,  Range: any.
Scales the amplitude of the bump map.

Bumps Threshold:   Default: 0,  Range: 0 or greater.
This value is subtracted from the Bumps input before it is used. It can be used to create flat areas resembling 'lakes.'

Bumps Smooth:   Default: 0,  Range: 0 or greater.
Smooths the noise texture before applying the Emboss. This can be helpful in removing unwanted artifacts from the noise generation algorithm.

Shift:   X & Y,   Default: [0 0],  Range: any.
Translation offset of the texture. Since the texture is procedurally generated it can be shifted with no repeating units or seams occurring.

Light Dir:   X & Y,   Default: [500 350],  Range: any.
The direction vector for the light source. Surface shading is calculated using light from this direction shining onto the generated bump map. This parameter can be adjusted using the Light Dir Widget.

Hilight Brightness:   Default: 0.5,  Range: 0 to 1.
Scales the brightness of the specular highlights.

Hilight Size:   Default: 0.5,  Range: 0.1 or greater.
Adjusts the size of the specular highlights.

Brightness:   Default: 1,  Range: 0 or greater.
Scales the brightness of the result.

Surface Color:   Default rgb: [0.75 0.75 0.75].
The color of the surface. The final color is affected by both this and the Light Color.

Light Color:   Default rgb: [1 1 1].
The color of the light source that creates the embossed result.

Bg Brightness:   Default: 1,  Range: 0 or greater.
The background brightness is scaled by this value before being combined with the texture.

Combine:   Popup menu,  Default: Screen.
Determines how the texture is combined with the Background.

Texture Only:  gives only the texture image with no Background.

Mult:  the texture is multiplied by the Background.

Add:  the texture is added to the Background.

Screen:  the texture is blended with the Background using a screen operation.

Difference:  the result is the difference between the texture and Background.

Overlay:  the texture is combined with the Background using an overlay function.

Show Light Dir: Check-box, Default: on.
Turns on or off the screen user interface for adjusting the Light Dir parameter.
