Lamp

Type

Types of lamps share all or some of the options listed here:

Color

The color of the light source’s illumination.

Energy

The intensity of the light source’s illumination from (0.0 to 10.0).

Distance

The Distance number button indicates the number of Blender Units (BU) at which the intensity of the current light source will be half of its intensity. Objects less than the number of BU away from the lamp will get more light, while objects further away will receive less light. Certain settings and lamp falloff types affect how the Distance is interpreted, meaning that it will not always react the same.

The Sun and Hemi Lamps are another class of Lamps which uses a constant falloff. Those lamps do not have a Distance parameter, and are often called „Base Lighting Lamps“.

Influence

Every lamp has a set of switches that control which objects receive its light, and how it interacts with materials.

Negative

Let the lamp cast negative light. The light produced by the lamp is subtracted from the irradiance on the surfaces it hits, which darkens these surfaces instead of brightening them.

This Layer Only

The Lamp only illuminates objects on the same layer the lamp is on. Causes the lamp to only light objects on the same layer.

Specular

The Lamp creates specular highlights.

Diffuse

The Lamp affects diffuse shading.
