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 clip to be processed. Bumps:  Optional.   The bump map for the emboss. Only the luminance of this input is used. Mask:  Optional.   If provided, the emboss is applied only at the areas specified by this input. This input can be affected using the Blur Mask, Invert Mask, or Mask 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. This parameter can be adjusted using the Light Dir Widget.

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

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

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

Luma:  the luminance of the RGB channels is used.

Alpha:  only the Alpha channel is used.

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