Using spot lights

Spot light emits light from a specific location towards a specified direction in the shape of a cone.

Spot lights work only with the materials that support spot lights in the shaders. In Kanzi these material types in <KanziInstallation>/Studio/Asset Library/MaterialTypes/General support two spot lights by default:

• PhongCube
• PhongTextured
• PhongTexturedCube
• PhongTexturedCubeNormalMap
• PhongTexturedNormalMap
• PhongTexturedShadowMap
• PhongTexturedSkinned

If you want to use more than two spot lights, you have to modify the shaders. See Editing shaders.

Creating spot lights

To create a spot light:

1. In the Project right-click the scene where you want to create a spot light and select Create > Spot Light.
2. Name the light and click OK.

Setting spot lights

The following are the most commonly used properties for setting a spot light:

• Color to set the color values of the light
• Attenuation properties to control the effect of the light on the objects that are farther away from the light
• Cutoff to set angle of light cone
• Exponent to set how the fully-lit area turns into a non-lit area
• Translation and Rotation properties to set the distance of the light from objects, and location and direction from which the point light emits light
