Sapphire Plug-ins for AVX2: Light3D

S_Light3D

Performs 3D relighting with up to 4 individually controlled light sources. The Source input is usually an ambient or diffuse pass from a 3d renderer that shows the surface colors. The Normal vector input determines the surface direction at each pixel. The source and normals should be generated together by the 3d program so they match.

In the Sapphire Lighting category.


Inputs:

Source: The current track. The 3d surface colors.

Normals: Selectable. Contains the normal vectors matching the Source clip. Typically the red channel will have the X component of the normal, green will have Y, and blue will have Z, but you can adjust this mapping using the Normal Offset and Invert parameters on the second page.

Background: Optional. The clip to use as background. The output of the effect is composited over this clip.

Mask: Optional. Used to interpolate between the original image and the result. Where the mask is black, no lighting is applied and the original Source image is visible.

Parameters:

Load Preset: Push-button .
Brings up the Preset Browser to browse all available presets for this effect.

Save Preset: Push-button .
Brings up the Preset Save dialog to save a preset for this effect.

Mocha: Default: 0, Range: 0 or greater.
Brings up the Mocha window for tracking footage and generating masks.

Blur Mocha: Default: 0, Range: 0 or greater.
Blurs the Mocha Mask by this amount before using. This can be used to soften the edges or quantization artifacts of the mask, and smooth out the time displacements.

Mocha Opacity: Default: 1, Range: 0 to 1.
Controls the strength of the Mocha mask. Lower values reduce the intensity of the effect.

Invert Mocha: Check-box,  Default: off.
If enabled, the black and white of the Mocha Mask are inverted before applying the effect.

Resize Mocha: Default: 1, Range: 0 to 2.
Scales the Mocha Mask. 1.0 is the original size.

Resize Rel X: Default: 1, Range: 0 to 2.
The relative horizontal size of the Mocha Mask.

Resize Rel Y: Default: 1, Range: 0 to 2.
The relative vertical size of the Mocha Mask.

Shift Mocha: X & Y,   Default: [0 0], Range: any.
Offsets the position of the Mocha Mask.

Bypass Mocha: Check-box,  Default: off.
Ignore the Mocha Mask and apply the effect to the entire source clip.

Show Mocha Only: Check-box,  Default: off.
Bypass the effect and show the Mocha Mask itself.

Combine Masks: Popup menu,  Default: Union .
Determines how to combine the Mocha Mask and Input Mask when both are supplied to the effect.
Union: Uses the area covered by both masks together.
Intersect: Uses the area that overlaps between the two masks.
Mocha Only: Ignore the Input Mask and only use the Mocha Mask.

Brightness: Default: 1, Range: 0 or greater.
Scales the brightness of all lights together.

Scales the diffuse brightness for Light 2 only.

Hilight Bright 2: Default: 1, Range: 0 or greater.
Scales the brightness of the specular highlights for Light 2 only.

Hilight Size 2: Default: 1, Range: 0 or greater.

If checked, inverts the depth compononent of the normal vectors.

Mask Parameters:

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.
