Light-wrap
Brief Description
Useful to composite objects into a background by spilling light from the background on the edges of the foreground objects.
Controls
| Parameter / Script Name | Type | Default | Function |
|---|---|---|---|
Enabled / enabled
|
Boolean | On | |
Red / process_red
|
Boolean | On | Enable the red channel in output. Otherwise if there's a source the content of the main source is returned instead, else 0. |
Green / process_green
|
Boolean | On | Enable the green channel in output. Otherwise if there's a source the main source content is returned, else 0. |
Blue / process_blue
|
Boolean | On | Enable the blue channel in output. Otherwise if there's a source the main source content is returned, else 0. |
Alpha / process_alpha
|
Boolean | On | Enable the alpha channel in output. Otherwise if there's a source the main source content is returned, else 0. |
Diffuse Size / diffuseSize
|
Float 2D | 15, 15 | Size of the background reflections. |
Intensity / intensity
|
Float | 2 | Controls the brightness of the reflections. |
Use Luminance-Based Wrap / useLuminance
|
Boolean | On | If disabled, the LightWrap is uniform instead of being affected by background luminance. |
Enable Glow / enableGlow
|
Boolean | Off | When enabled, the wrap is not masked by the foreground, creating a glow. |
Foreground Blur Size / fgBlur
|
Float 2D | 1, 1 | Blur applied to the foreground alpha matte; higher values leak more background. |
Foreground Blur Border / fgBorderMode
|
Choice | Black | Repeat
Black Repeat RGB Black Alpha |
Background Blur Size / bgBlur
|
Float 2D | 0, 0 | Blur applied on the background before merging and diffuse blur. |
Luma Tolerance / lumaTolerance
|
Float | 1 | Luminance threshold; below this value pixels do not generate lightwrap. |
Blend Mode / blendMode
|
Choice | Add |
Add: Ac + Dc — adds source to destination. Color Dodge: if Ac < 1 → min(1, Bc/(1 − Ac)); else 1. Lighten: max(Ac, Bc). Linear Dodge: min(Ac + Bc, 1). Screen: Ac + Bc − Ac×Bc. Hard-light: multiply/screen depending on Ac. Hard Mix: vivid‑light threshold. Linear Light: burn/dodge depending on Ac. Overlay: multiply/screen depending on Bc. Pin Light: removes mid‑tones. Soft Light: multi‑branch soft‑light model. Vivid Light: burn/dodge mix. Difference: abs(A − B). Divide: Ac / Bc (if valid). Exclusion: Ac + Bc − 2AcBc. Minus: Ac − Bc. Subtract: Bc − Ac. Color: SetLum(Ac, Lum(Bc)). Hue: SetLum(SetSat(Ac, Sat(Bc)), Lum(Bc)). Luminosity: SetLum(Bc, Lum(Ac)). Saturation: SetLum(SetSat(Bc, Sat(Ac)), Lum(Bc)). Replace: Ac. Destination Atop: Bca×Aa + Aca×(1−Ba). Destination Out: Ba×Bc×(1−Aa). Destination Over: Aa×(1−Ba) + Bc. Destination In: Bc×Aa. Source Atop: Ac×Ba + Bc×(1−Aa). Source Out: Ac×(1−Ba). Normal: Ac + Bc×(1−Aa). Source In: Ac×Ba. Xor: Ac×(1−Ba) + Bc×(1−Aa). Average: (Ac + Bc)/2. Conjoint Over: depends on Aa ≤ Ba. Disjoint Over: depends on Aa + Ba ≥ 1. Geometric: 2AcBc/(Ac + Bc). Grain Extract: Bc − Ac + 0.5. Grain Merge: Bc + Ac − 0.5. Hypot: sqrt(Ac² + Bc²). Reflect: Aa²/(1−Ba). Color Burn: 1 − min(1, (1−Bc)/Ac). Darken: min(Ac, Bc). Linear Burn: Bc + Ac − 1. Multiply: Ac × Bc. Multiply (Math): Ac × Bc (negatives preserved). |
Background Source / colorMode
|
Choice | Previous Layer |
When set to Previous Layer, the spill comes from the prior layer; Custom Image uses a user‑selected image. Previous Layer Custom Image Constant Color |
Background Image / backgroundImage
|
Image | - | The image used as background. |
Constant Color / constantColor
|
Color | 1, 1, 1, 1 | The constant color used when Color Mode is set to Constant Color. |
Mask / mask
|
Image | - | |
Mix / mix_with_source
|
Float | 1 | Dissolves between the original image (0) and the effect (1). |
