SpeedSix.Candle (Discreet Box9)
PURPOSE
Simulating a flame; from a single guttering candle flame to an inferno.
INPUT CLIPS
1: Background
: Clip over which flames are to appear.
2: Matte
: Clip that can be used to control where the flames appear.
Candle CONTROL PAGE
Offset (Position Default: 0.5,0.5)
Width (Number Min: 0.001, Max: 5.0, Default: 0.6)
Use Matte (Checkbox Default: Off)
Modulate the density of the flames using the luminance of the matte clip.
Invert Matte (Checkbox Default: Off)
Reverse the luminance and thus the resulting densities of the flames.
Seed (Number Min: 1, Max: 999, Default: 22)
Change for a different starting point within the turbulence. Keep the same seed for repeatability.
Top (Number Min: -5.0, Max: 5.0, Default: 0.3)
These controls define the flame generation area. Flames are created within this box but subsequent forces such as wind, may cause them to over-shoot this box.
Bottom1 (Number Min: -5.0, Max: 5.0, Default: 0.3)
Bottom2 (Number Min: -5.0, Max: 5.0, Default: 0.35)
Bottom3 (Number Min: -5.0, Max: 5.0, Default: 0.4)
Bottom4 (Number Min: -5.0, Max: 5.0, Default: 0.25)
These points define the base profile of the flame.
Base Softness (Number Min: 0.0, Max: 100.0, Default: 10.0)
Softens the base of the flames.
Edge Softness (Number Min: 0.0, Max: 100.0, Default: 30.0)
Softens the edges of the flames.
Flame Density (Number Min: 0.0, Max: 100.0, Default: 100.0)
Overall opacity of the flame.
Convection (Number Min: 0.0, Max: 100.0, Default: 40.0)
The speed with which the flames move upwards through the turbulence.
Flicker Speed (Number Min: 0.0, Max: 100.0, Default: 50.0)
The speed with which the flames move forwards through the turbulence. If the Convection is set to 0.0 then the flames will still evolve (if Flicker is greater than 0.0) but with no upwards motion.
Turbulence (Number Min: 0.0, Max: 100.0, Default: 40.0)
Turbulence disturbs the flame; at 0.0 a pure steady flame, distorting the flame as it increases.
Frequency 1 (Number Min: 0.0, Max: 100.0, Default: 30.0)
Frequency 2 (Number Min: 0.0, Max: 100.0, Default: 70.0)
Defines the internal features of the turbulence of the flame. The ratio of the two frequencies defines the structure combined with the turbulence value. Swapping frequency values results in the same flame patterns.
Tip: If the turbulence is low and both the frequencies are low the flames are broad and sweeping; with the turbulence high and both frequencies high the flames are finely detailed. As the frequencies become closer together the detailing gets less.
Demos (List Box Options: Evens | Edge | Centre | Still | Soft | Wiggly | Wild | Fluffy, Default: Evens)

Wind CONTROL PAGE
Wind (Checkbox Default: Off)
Turn on the wind feature.
Wind Source (Position Default: 0.95,0.15)
Wind Target (Position Default: 0.3,0.4)
Wind Spread (Number Min: 0.0, Max: 180.0, Default: 60.0)
The wind blows from the source, towards the target within the cone defined by the spread.
Wind Speed (Number Min: 0.0, Max: 100.0, Default: 30.0)
How forcefully the wind is blowing.
Colour CONTROL PAGE
Core Colour (Colour Box Default: R: 65535, G: 65535, B: 65535, A: 35535)
Proportion Col 1 (Number Min: 0.0, Max: 100.0, Default: 50.0)
Centre Colour (Colour Box Default: R: 64320, G: 64320, B: 320, A: 35535)
Proportion Col 2 (Number Min: 0.0, Max: 100.0, Default: 50.0)
Edge Colour (Colour Box Default: R: 65535, G: 320, B: 320, A: 35535)
Proportion Col 3 (Number Min: 0.0, Max: 100.0, Default: 50.0)
The flames comprise of 3 colour regions in varing proportions. The distribution of the flame colours can be weighted. With all three at 50.0 the three colours are distributed evenly throughout the flame. The ratio of the three numbers will change the balance of distribution. e.g. to extend the core colour, increase Proportion Col 1.
