Photometric Lights



The Target Point Light (Photometric)

The Target Point Light works similarly to a standard Omni Light. Light is emitted from a geometric point. When you create a Target Point Light, a LookAt constraint will be automatically set up for you.

The Free Point Light (Photometric)

The Free Point Light works exactly like the Target Point Light, but has no target and uses transforms to aim it.

The Target Linear Light (Photometric)

The Target Linear Light uses a line to emit light, much like a flourescent tube. When you create a Target Linear Light, a LookAt constraint will be automatically set up for you.

The Free Linear Light (Photometric)

The Free Linear Light uses a line to emit light, much like a flourescent tube. Transforms are used to aim the light.

The Target Area Light (Photometric)

The Target Area Light emits light from a rectangular area. When you create a Target Area Light, a LookAt constraint will be automatically set up for you.

The Free Area Light (Photometric)

The Free Area Light emits light from a rectangular area. Transforms are used to aim this light instead of a target.

The IES Sun Light (Photometric)

This light works with a daylight system to provide accurate sunlight effects based on location, time and date. This complex light bears the name of its creator, the IES (Illuminating Engineering Society).

The IES Sky Light (Photometric)

This light is usually used with a daylight system, combining the effects of sunlight and atmospheric effects in the sky. Like the IES Sun Light, it uses principles of the Illuminating Engineering Society. In order to function, it must point down the Z-axis, and Final Gather is enabled.
