Sapphire Plug-ins for Autodesk: Light3D

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.

Inputs:

Source: The 3d surface colors.

Normals: 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.

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.

Red: Use Red channel.
Green: Use Green channel.
Blue: Use Blue channel.

Invert X: Check-box,  Default: off.
If checked, inverts the horizontal compononent of the normal vectors.

Invert Y: Check-box,  Default: off.
If checked, inverts the vertical compononent of the normal vectors.

Invert Z: Check-box,  Default: off.
If checked, inverts the depth compononent of the normal vectors.

Normal Offset: Default: -0.5, Range: any.

Light3 Enable: Check-box,  Default: off.
Enables the third light source.

Light3 Color: Default rgb: [1 1 1].
The color of the third light source.

Diffuse Bright 3: Default: 1, Range: 0 or greater.

Hilight Bright 3: Default: 1, Range: 0 or greater.
Scales the brightness of the specular highlights for Light 3 only.

Hilight Size 3: Default: 1, Range: 0 or greater.
Adjusts the size of the specular highlights for Light 3 only.

Light3 Z: Default: 0.5, Range: any.
The z position of the third light source.

Light4 Enable: Check-box,  Default: off.
Enables the fourth light source.

Light4 Color: Default rgb: [1 1 1].

Params3:

Light1 Dir: X & Y,   Default: [-0.7 0.6], Range: any.
The x and y position of the first light source. This parameter can be adjusted using the Light1 Dir Widget.

Light3 Dir: X & Y,   Default: [-0.7 -0.6], Range: any.
The x and y position of the third light source. This parameter can be adjusted using the Light3 Dir Widget.

Light2 Dir: X & Y,   Default: [0.7 0.6], Range: any.
The x and y position of the second light source. This parameter can be adjusted using the Light2 Dir Widget.

Light4 Dir: X & Y,   Default: [0.7 -0.6], Range: any.

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

Blur Mocha: Default: 0, Range: 0 or greater, Shared .
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, Shared .
Controls the strength of the Mocha mask. Lower values reduce the intensity of the effect.

Invert Mocha: Check-box,  Default: off, Shared .
