Brightness

Multiplies the brightness of every point in a frame by a single scalar. The simplest way to fade a frame in or out without touching its color, geometry, or path order.

Inputs

Port	Type	Default	Range	Description
Frame	Frame	—	—	The frame to dim
Brightness	Scalar	1.0	0–1	Brightness multiplier. 1.0 is unchanged, 0 is fully dark

Outputs

Port	Type	Description
Frame	Frame	The dimmed frame

Ideas

Animate Brightness with a Phasor or Envelope to fade a clip in and out on a cue.
Wire an Audio Input (Loudness mode) into Brightness for a frame that pulses with the music.
Use as a master gate on a section of the graph: route the frame through Brightness before Output to gate the whole scene with one signal.

Tips

Brightness is sampled once per frame, not per point. All points scale by the same factor.
The node is a no-op when Brightness equals 1.0. It returns the input frame untouched, so leaving it in the graph has no cost.
Values above 1 are clamped to 1; values below 0 are clamped to 0.

Colorize: apply a color while preserving source brightness instead of scaling it
Laser Chase: per-laser brightness sweep, not a global multiplier
Output: final transform after the frame is dimmed
