The Hair Light Attr(ibutes) rollout lets you adjust properties for the hair shadow
map generated by the light. This rollout appears for supported lights at render
time. If you want to adjust a light's hair settings before render time, you can
display it explicitly by following the steps shown in the path annotations at
the beginning of this topic.
You specify which lights to use in the
Hair And Fur render effect on page 6588.
By default,
Use All Lights At Render Time on page 6593 is on, so all supported
lights in the scene can illuminate hair. Use this rollout to set hair-specific
shadow-map values. Hair shadows ignore the light's ordinary shadow-map
settings (for other 3ds Max objects).
IMPORTANT The settings on this rollout apply only to “buffer”-rendered hair (the
default rendering method, set in the Hair And Fur render effect). The “geometry”
and “mr prim” methods use the light's ordinary shadow settings.
Interface
Light hair When on, the light can illuminate and cast shadows from the hair.
NOTE The light must also be set to cast shadows (General Parameters rollout >
Shadows > On).
Resolution Sets the size (in pixels squared) of the shadow map that's computed
for the light.
The shadow map size specifies the amount of subdivisions for the map. The
higher the value, the more detailed the map will be, but the more memory is
required.
Fuzz Sets the softness of the shadow edges. See
Sample Range on page 8111.
