Club effect

UV Reactor

UV Reactor is a club lighting look in FRCTL, the browser VJ studio. Blacklight violet washed with cobalt, cyan and acid yellow.

Runs live on video, images, a camera or generated art. Stack it with any other effect, and route LFOs, envelopes or any of ten audio bands to its controls so it moves with the music.

What UV Reactor does

Lights the picture like a blacklight: shadows go violet into cobalt, greens and blues flip to cyan, and the brightest tones burn acid yellow. Stops raises the cyan and yellow washes together, and Glow adds a violet-tinted shine on the source's own highlights, the way white fabric flares under UV. There's no pink or lime here, which sets it apart from Neon Abyss.

Using UV Reactor

Where it works: Psytrance and blacklight-party flyers, where fluoro yellow and cyan on blue is the house look. It's also a quick match for UV-painted decor in venue footage.
With the music: No built-in reaction. B8 (hats) on Glow makes the highlights shimmer with the hi-hats, and an audio-triggered Envelope on Stops floods cyan and yellow on each hit before dropping back to violet.
Starting point: Blend three-quarters, Glow centre, Stops centre, then pull Stops toward a quarter if the yellow swallows the midtones.

Controls

Blend: Strength of the filter vs source.
Glow: Pow-specular highlight lift.
Stops: Cyan and acid mix weights vs luminance.
