Lighting group
These settings control the illumination of hair and shadow-casting from hair
by supported lights in the scene.
The following light types 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 Area Spot, mr Sky, and mr Sun
are supported for hair when you use the “mr prim” method and the mental
ray renderer.
NOTE For the purposes of rendering shadows in hair, Direct lights are treated as
point (omni) lights.
Shadow Density Specifies the relative darkness of the shadows. At the default,
highest 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
Attr(ibutes) rollout
on page 5076 Default=on.
NOTE These settings apply only to “buffer”-rendered hair (the default type, set
in the Hair Rendering Options group, as described above).
Add hair properties Adds the Hair Light Attr(ibutes) rollout on page 5076 to
selected lights in the scene. If you want to assign hair-specific shadow
properties on a per-light basis, this rollout is necessary. Available only when
at least one supported light is selected.
When Use All Lights At Render Time is off, only lights with hair properties
can illuminate hair.
Remove hair properties Removes the
Hair Light Attr(ibutes) rollout on page
5076 from selected lights in the scene. Available only when at least one light
with hair properties added is selected.
