Lighting in 3ds Max
Lighting in 3ds Max simulates natural lighting. However, standard lights are
simpler than natural lighting. Using
photometric lights on page 5005 with a
radiosity solution on page 6168 with your lights provides a better model of the
real world.
Intensity
The intensity of a standard light is its HSV Value. At full value (255), the light
is at its brightest; at 0, the light is completely dark.
NOTE See Designing Materials on page 5260 for more information about material
color and how it interacts with light intensity.
The intensity of a photometric light is set by a real-world intensity value,
measured in either lumens, candelas, or lux. See
Intensity/Color/Attenuation
Rollout (Photometric Lights)
on page 5037.
Angle of Incidence
3ds Max uses a vector from the light object to the face, along with the face
normal, to calculate the angle of incidence.
A surface is fully illuminated when the angle of incidence is 0 degrees (that
is, the light source strikes the surface perpendicularly). If the angle of incidence
