HairEffect : RenderEffect
HairEffect - superclass: renderEffect; super-superclass:MAXWrapper - classID: #(988153529, 337462665)
The HairEffect RenderEffect available since 3ds Max 8 is responsible for the rendering of the hair.
Constructor:
| USAGE
|
s=sphere()
theHair = HairEffect()--create an instance of the effect
addEffect theHair--add to the listin theEffects dialog
--BUT!
--Adding a Hair WSM to a scene object will add
--a HairEffect to the list automatically!
--Thus, you can simply get the existing one:
addModifier $Sphere001 (HairMod())--add Hair WSM to Sphere001
--At this point, if no HairEffect exists in the Effects dialog,
--it will be added automatically. Let's find it by going through
--all effects by index and asking each one for its class:
theEffects = (
for i = 1 to numEffects where classof (getEffect i) == HairEffect collect (getEffect i)
)
--At this point we should have at least one HairEffect.
--Let's take the first one:
if theEffects.count > 0 do theHair = theEffects[1]
