Material Parameters Rollout (Hair
and Fur)
Select an object with the Hair And Fur modifier applied. >
Modify panel > Material Parameters rollout
The parameters on this rollout apply to
buffer-rendered h air generated by Hair. In the
case of geometry-rendered hair, the hair coloring
is derived from the growth object. In the case of
hair rendered by “mr prim”, all par ameters apply
except Self Shadow and Geom. Shadow. With
instanced hair, Hair uses the material from the
instanced object.
Youcanapplyamaptoanyvaluebyclickingthe
blank button to the right of the parameter. Values
in the map act as multipliers to the base value.
Tip: If you apply a colored texture map to a color
attribute such as Tip Color, start by setting the
base color to white. Because the m ap acts as a
multiplier, not doing so can lead to unexpected
results. For example, if Tip Color is set to yellow
and you apply a blue texture map, the hair wi ll be
black: this is because if you multiply those RGB
values, they zero each other out.
Interfa ce
Occluded Amb.—Cont rols the bias of the
ambient/diffuse contributions of the illumination
model. A setting of 100.0 renders the hair with flat
lighting. A value of 0.0 is lit only by scene light
sources, typically resulting in a h igher-cont rast
solution. Default=40.0. Range=0.0 to 100.0.
