Candle Flicker

Creates a candle flicker effect.

Overview

The Candle Flicker effect was designed to simulate the effect of a candle flickering. It has many settings to adjust how the flicker behaves.

Configuration

  • Group Level Controls how many elements in the group have the same flicker applied to them. Elements are grouped in blocks of this size, and every element in a block shares the same randomly generated flicker pattern. Range is 1-5000. Defaults to 1, meaning each element gets its own unique flicker.

Color

  • Color Sets the single solid color used for the flicker. Unlike some other effects, Candle Flicker does not support a Color Gradient — only brightness is varied over time.

Brightness

  • Max Controls the maximum brightness a flicker can reach. This is a 0-100 percent range of the overall color brightness. Default is 100%.
  • Min Controls the minimum brightness a flicker can drop to. This is a 0-100 percent range of the overall color brightness. Default is 10%.

Flicker

The flicker is generated as a series of random brightness steps between the Min and Max brightness. Each step has a duration and a size, and both are randomized around the values below so that no two flickers look exactly alike.

  • Frequency Sets the baseline flicker rate, in changes per second. For example, a value of 20 targets a new brightness step roughly every 1000/20 = 50 ms on average. The actual duration of each step is then randomized using Flicker below. Default is 20.
  • Change Percent Sets the average size of each brightness step, as a percentage of the overall brightness range. The actual size of each step is then randomized using Deviation below, and each step is randomly chosen to move brightness up, down, or not at all. Default is 20%.
  • Flicker Sets how much the timing of each step can randomly deviate from the Frequency setting, as a percentage. Higher values make the flicker’s timing less regular. Default is 25%.
  • Deviation Sets how much the size of each brightness step can randomly deviate from the Change Percent setting, as a percentage. Higher values make the flicker’s intensity less consistent. Default is 50%.
