RACE AMBIANCE FX · SIMHUB PLUGIN

The ambiance of the race,
right in your room.

Race Ambiance FX is a SimHub plugin that drives your ambient light bars from what's outside your car's glass: headlight sweeps, flag stands, dusk falling over the circuit. It works out where each car's windows are while you drive, remembers the car, and adjusts itself between night and day. No zones to draw, no mapping to maintain.

It learns the glass, not the screen.

Sample the whole monitor and you light the room with your dashboard, mirrors and HUD as much as the track. Race Ambiance FX works out where your car's windows are while you drive, and lights your room from what's actually outside them. Switch cars and it learns the new cockpit too, then remembers each one. You never draw a zone.

Night races look like night. Because it noticed.

A response tuned for a floodlit straight looks wrong at noon, and vice versa. Race Ambiance FX crossfades its own response as the scene shifts between day and night. Le Mans at 3 a.m. reads differently than Sebring at 2 p.m., and you never touch a slider mid-stint.

When something moves on screen, it moves in your room.

Ambient light only sells the illusion if it keeps up. Race Ambiance FX reacts to on-screen motion around thirty times a second, and it keeps track of direction: a car passing on your left passes on your left.

The actual software.

Not a mock-up. This is a real capture of the plugin running inside SimHub.

Race Ambiance FX in Simple mode: rig status with guided setup, five presets, and four sliders for brightness, colour richness, light sensitivity and response smoothing
Simple mode is the whole interface, for most people.

A rig status you can read at a glance, five presets, called Default, Night race, Day race, Endurance and Rally, and four sliders. Every slider runs 0–100% with the tuned default at 50%, and changes apply live while you drive.

Advanced mode, Cockpit learning: a real learned mask for a Mercedes-AMG GT2 overlaid on a triple-screen game frame, showing green cockpit blocks, red window blocks and the side mirror carved out
The learned mask, made visible.

Green is the cockpit, red is the world through the glass. This Mercedes-AMG GT2's mask was learned while driving, not drawn. Every car gets its own, kept in a learning library you can review, retake or reset, and the bars can follow the cockpit's reflected glow, the windows, or the whole screen.

Advanced mode, Race flags and pit limiter: per-flag colour, style and speed settings, each with a test button
Race flags, on your real lights.

When the sim shows a marshal flag, the bars take over until it clears. Every flag has its own colour, style and speed, plus a Test button that fires your actual bars right now, with no session needed.

The boring reliability stuff.

  • Per-car memory. The cockpit mask and interior colour are stored per car. Come back to a car next month and it's already dialed in.
  • Interior colour, your way. Learned automatically from the car, or set your own.
  • Self-healing layout. Unplug a bar, plug it back in, and it re-aligns without a trip to settings.
  • Your rig. Single, ultrawide and triple-monitor setups.
  • Your lights. Govee, Philips Hue, Adalight, and anything else SimHub's Ambient Lights supports.
  • Requirements. Windows, SimHub. It reads the game via live screen capture, so it lights your room from what you actually see.

Measured, not vibes.

Reactivity isn't tuned by eyeballing a wall. Race Ambiance FX is tuned against recorded race footage played back and measured, so how hard the bars react to what is on screen was settled with data rather than guesswork.

Measured from the plugin's own output rather than filmed off a wall, so the result isn't skewed by a camera's auto-exposure.
