A Spotlight emits a cone of light. You have control over the direction the light is pointing and the spread of the light by specifying the angle of the cone.

When you place a Spotlight in Shaderlight it is marked by a Spotlight component. The yellow dot indicates the source of the light and the white triangles indicate the direction and size of the light cone. You can select, move and rotate the component in your scene to place the source of the light, but the component itself won't appear in your Shaderlight image.

Spotlight Properties

 

You can change the intensity, spread and color of the spotlight.

 

Intensity – The intensity of the spotlight is set in candela and the default value of 125 candela is roughly the light emitted by a 100 watt tungsten light bulb. (One candela is roughly the amount of light emitted in any given direction by a "standard" candle)

 

Spread – The spread is controlled by the angle of the cone of light emitted by the spotlight. The white triangles of the spotlight icon change to indicate the size of the spread angle

 

Color – The color of the light can be changed using the color sliders (either HSB or RGB) and can be seen in the color swatch at the top left of the window.
