any slider , it mixes with the values of the other
two, and the result appears in the s watch beneath
the sliders.
For example, if you move the Red slider all the way
to the right (value 255) and leave the other two at
the left (0), the active swatch t u rns red. If you then
move the Green slider all the way to the right, the
swatch turns yellow. If you move all three sliders
to 0, the result is black; if all three are at 255, the
result is white; and all three at any point of equal
value produce shades of gray.

If you prefer the hue/saturation/value color
system, you can use the HSV sliders to m ix color.

Saturation slider to determine the purity of the

color.
Reference
Referencesarelike"one-way"instances.
Referenced objects are based on the original
object, as are instances, and can have their own
unique modifiers. Any modification made to the
original object is passed on to its references, but
any modification made to a reference is not passed
back to the original.
The one-way effect is useful, since you can
maintain an original that will affec t all its
references, while the references themselves can
take on individual characteristics.
If you are modeling heads, for example, you
mightwanttokeepafamilyresemblanceinyour
characters. You could model basic features on the
original, then model specifics on each reference.
In the modifier stack, a solid line separates the
reference from its parent object, so you can see that
the effect of modifiers on the reference will not
affect the parent object or other references to it.
Reference Object
In Particle Flow (p age 2–105) , a reference object
is a geometr y object or collection of objects
used as par ticles by the
Shape Instance operator
(page 2–174)
.Itcanbeasingleobject,agroup,a
hierarchy, or even a compound object consisting
of several elements.
Refine
In NURBS modeling, refining means to inc rease
the number of CV s on a curve or surface. Refining
does not change the curvature of the curve or
surface.
Reinitialize
In Phys ique (page 2–927) , when you need to reset
vertex, envelope, and other skin parameters, click
Reinitialize to display the
Physique Initialization
dialog (page 2–964)
. Using controls in this dialog,
you select which category to update, and apply the
new global settings you specify.
For example, if you’ve added a new bone to the
hierarchy and want it included and influenced by
