What the Light Affects

Lamp panel with the light affecting options highlighted

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

Negative

The light produced by the lamp is subtracted from the one “available” on the surfaces it hits, which darkens these surfaces instead of brightening them.

This Layer Only

Causes the lamp to only light objects on the same layer.

Diffuse

Prevents the lamp from producing diffuse light (it doesn’t really “light” things).

Specular

Prevents the lamp from producing specular highlights.
