Lighting group
These settings control the illumination of hair and
shadow-casting from hair by supported lights in
the scene.
The following light t ypes are not supported when
rendering hair with the “buffer” method: Skylight,
mr Area Omni, mr Area Spot, IES Sun, IES Sky,
mr Sky and mr Sun. However, mr Area Omni, mr
AreaSpot,mrSky,andmrSunare supported for
hair when you use the “mr prim” metho d and the
mental ray renderer.
Note: For the purposes of rendering shadows in
hair, Direct lig hts are treated as point (omni) lights.
Shadow Density—Specifies the relative darkness of
the shadows. At the default, hi ghest value, 100.0,
shadows are darkest. At the lowest value, 0.0,
shadows are fully transparent, so they don’t render.
Range=0.0 to 100.0. Default=100.0.
Use all lights at render time—When on, causes all
supported lights in the scene to illuminate and cast
shadows from hair when the scene is rendered.
(Shadows are cast only from lights whose Shadows
toggle is on.) When off, for a light to cast shadows
from hair, you explicitly must add hair properties.
In either case, shadow maps for hair use the
settings from the Hair Light A ttr(ibutes) rollout
(page 2–1351) Default=on.
Note: These sett ings apply only to
“buffer”-rendered hair (the default type,
set in the Hair Rendering Options group, as
described above).
Add ha ir proper ties—Adds the Hair Light
Attr(ibutes) rollout (page 2–1351) to selected lights
in the scene. If you want to assign hair-specific
shadow properties on a per-light b asis, this rollout
is necessary. Available only when at least one
supported light is selected.
When Use Al l Lights At Render Time is off, only
lights with hair propert ies can illuminate hair.
Remove hair proper ties—Removes the Hair Light
Attr(ibutes) rollout (page 2–1351) from selected
ligh ts in the scene. Available only when at least one
lightwithhairpropertiesaddedisselected.
