Glow

Filterv1coreNeeds full input

Overview

Adds a soft bloom around bright areas. Threshold picks what glows.

How to

How-to

Set threshold so only the highlights bloom, then size and intensity for the halo.
Use tint to colour the glow; the picture underneath is untouched.
Start from a preset on the node for the usual looks.

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`
radius	Float	12.0	Size of the effect, in pixels.
threshold	Float	0.5	Only pixels brighter than this glow.
intensity	Float	1.0	How strong the added effect is.
quality	Choice	box	box: a single blur (fast). optical: a stack of blurs with falloff — a tight core and a wide faint wash at once, the real lens look. `boxoptical`
mode	Choice	screen	How the glow lands: screen (never over white) or plus (additive, can exceed 1). `screenplus`
levels	Int	6	optical: how many blur octaves the wash spans.
falloff	Float	0.6	optical: how much each wider octave dims. Lower = wider reach.
chromatic	Float	0.0	Spread the octaves by wavelength — a coloured fringe on the wash, like a real lens.
tint	Color	[1.0, 1.0, 1.0, 1.0]	Colour the glow.
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).
