Overview
The background's light bleeding around the keyed foreground's edge - the node every keying tutorial hand-builds from a Blur, an edge band and a Merge. Wire the keyed FG into in, the BG into bg, place it before the final merge over.

Inputs
| Input | What it takes |
|---|---|
| in | the image this node works on |
| bg | a clean background to reveal (optional — without one the node estimates it and says so) |
| mask | limits the effect to this matte — the engine's universal mask slot, applied for every node that declares it |

Parameters
| Parameter | Type | Default | What it does |
|---|---|---|---|
| channels | Choice | rgba | Which channels this node writes: rgba, rgb (alpha passes through untouched), alpha only, all, or none (bypass). Everything unselected comes straight from the input — same as Nuke. allrgbargbalphanone |
| diffuse | Float | 20.0 | How far the wrap reaches inside the silhouette, in pixels. |
| bg_blur | Float | 30.0 | How soft the borrowed background light is, in pixels - bigger reads as ambience, smaller as a rim. |
| intensity | Float | 1.0 | How much of the background's light arrives. |
| operation | Choice | screen | screen glows filmically and can never blow out (HDR-guarded above 1.0); plus is honest scene-linear addition. screenplus |
| wrap_only | Bool | false | Show just the wrap with its edge band in the alpha - check the reach before committing. |
| disabled | Bool | false | Bypass: the node passes its first input through untouched (D in the graph). The knobs keep their values for when it comes back. |
| label | Text | A note shown under the node in the graph — what this node is FOR. Never affects the render or the cache. | |
| hide_input | Bool | false | Draw the node without its input wire — a tidy graph for a node whose source is obvious (a Dot, a viewer tap). |
