Photometric Linear and Area Lights have rollouts

specific to them:

Linear Light Parameters Rollout (page 2–1354)

Area Light Parameters Rollout (page 2–1354)

Preset Lights are photometric lights that have a

preset configuration in 3ds Max. Preset Lights

load up correct values based on their equivalent

commercial produc t. For example, a 60W light

setting loads up the correct intensity, lighting ,

and distribution settings corresponding to a real

60W bulb. Using Preset Lights, you’re able to

quickly create lights that are correct simulations of

real-world objects.

The Preset Lig hts available are:

• Generic 60W Bulb

• Generic 75W Bulb

• Generic 100W Bulb

• Generic Recessed 75W Lamp (web)

• Generic Recessed 75W Wallwash (web)

• Generic Recessed 250W Wallwash (web)
