Uniform diffuse light distribution
NOTE Uniform Diffuse distribution was known simply as Diffuse distribution in
releases prior to Autodesk 3ds Max 2009.
Spotlight Distribution (Photometric Lights)
Create panel > Lights > Photometric Lights > Click Target Light or Free Light.
> General Parameters rollout > Light Distribution (Type) group > Choose
Spotlight from the drop-down list.
A spotlight distribution casts a focused beam of light like a flashlight, a follow
spot in a theater or a headlight. At the light's beam angle, intensity has fallen
to 50 per cent. At the field angle, the intensity fades to a value near zero.
NOTE The beam angle is similar to the hotspot angle for standard lights, but all
of a hotspot is at 100 per cent intensity. The field angle is similar to the falloff
angle for standard lights, but at the falloff angle, intensity fades to zero;
photometric lights use a smoother curve, so some light might be cast outside the
field angle.
