## Shader Properties

### Color

Parameter ID: `SUNBURSTSHADER_COLOR`

The gradient determines the color of the sunburst.

### R Frequency

Parameter ID: `SUNBURSTSHADER_SCALE_R` · Range: [0.00..+∞]

Determines the radial frequency; a value of 0 yields an attractive aurora.

### A Frequency

Parameter ID: `SUNBURSTSHADER_SCALE_A` · Range: [0.00..+∞]

Gives the angular disturbance; 0 gives individual layers.

### T Frequency

Parameter ID: `SUNBURSTSHADER_FREQUENCY` · Range: [0.00..+∞]

Defines the speed of the sunburst; 2 doubles it, 0 prevents all movement.

### Turbulence

Parameter ID: `SUNBURSTSHADER_TURBULENCE` · Range: [0.00..+∞]

Changes the appearance of the eruption; the higher the value, the more fragmented this region appears.

### Radius

Parameter ID: `SUNBURSTSHADER_RADIUS` · Range: [0..100%]

Defines where the eruption begins, as a percentage of the overall size.

### Height

Parameter ID: `SUNBURSTSHADER_HEIGHT` · Range: [0..100%]

Defines the width of the eruption region relative to the radius.
