S_Emboss Embosses the Source clip using the brightness of the Bumps input as a relief map. Increase the Bumps Smooth parameter for bolder bumps, and adjust the Light Dir to illuminate the bumps from different angles. In the Sapphire Stylize effects submenu. Inputs: Source:  The current layer.   The clip to be processed. Bumps:  Defaults to None.   The bump map for the emboss. Only the luminance of this input is used. Matte:  Defaults to None.   If provided, the emboss is applied only at the areas specified by this input. This input can be affected using the Blur Matte, Invert Matte, or Matte Use parameters.

Parameters:

Light Dir:   X & Y,   Default: [180 360],  Range: any.
The direction vector for the light source. Surface shading is calculated using light from this direction shining onto the Bumps input.

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

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

Bumps Scale:   Default: 1,  Range: any.
Scales the amplitude of the bump map.

Bumps Threshold:   Default: 0,  Range: 0 to 1.
This value is subtracted from the Bumps input before it is used.

Bumps Smooth:   Default: 0,  Range: 0 or greater.
If positive, the Bumps input is blurred by this amount before being used. Increase for a softer emboss effect.

Subpixel Smooth:   Check-box,  Default: off.
If enabled, the amount of pre-smoothing of the Bumps input is performed at subpixel accuracy. It can be helpful if Bumps Smooth is very small or is being animated. This parameter has no effect unless Bumps Smooth is positive.

Blur Matte:   Default: 0,  Range: 0 or greater.
Blurs the Matte input by this amount before using. This can provide a smoother transition between the matted and unmatted areas. It has no effect unless the Matte input is provided.

Invert Matte:   Check-box,  Default: off.
If on, inverts the Matte input so the effect is applied to areas where the Matte is black instead of white. This has no effect unless the Matte input is provided.

Matte Use:   Popup menu,  Default: Luma.
Determines how the Matte input channels are used to make a monochrome matte.

Luma:  the luminance of the RGB channels is used.

Alpha:  only the Alpha channel is used.

Opacity:   Popup menu,  Default: Normal.
Determines the method used for dealing with opacity/transparency.

All Opaque:  Use this option to render slightly faster when the input image is fully opaque with no transparency (alpha=1).

Normal:  Process opacity normally.

As Premult:  Process as if the image is already in premultiplied form (colors have been scaled by opacity). This option also renders slightly faster than Normal mode, but the results will also be in premultiplied form, which is sometimes less correct.
