3ds Max generates the mapping coordinates in
the U and V dimensions. The U coordinate
w raps once around the spline; the V coordinate is
mappedoncealongitslength.Tilingisachieved
using the Tiling parameters in the applied material.
For more information, see Mapping Coordinat es
(page 2–1405).
Real-World Map Size—Controls the scaling method
used for texture mapped materials that are applied
totheobject. Thescalingvaluesarecontrolled
by the Use Real-World Scale settings found in
the applied material’s Coor dinates rollout (page
2–1625).Default=on.
Auto S mooth—If Auto Smooth is turned on, t he
spline is auto-smoothed using the threshold
specified by the Threshold setting below it. Auto
Smooth sets the smoothing based on the ang le
between spline segments. A ny two adjacent
segmentsareputinthesamesmoothinggroupif
the angle between them is less than t he threshold
angle.
Threshold—Specifies the threshold angle in
degrees. Any two adjacent spline segments are put
inthesamesmoothinggroupiftheanglebetween
them is less than the threshold angle.
ViewportTurn this on to specify Radial or
Rectangular parameters for the shape as it will
display in the v iewport when Enable in Viewport
is turne d on.
R end er erTurn this on to specif y Radial or
Rectangular parameters for the shape as it will
displaywhenrenderedorviewedintheviewport
when Enable in Viewport is turned on.
RadialDisplays the 3D mesh as a cylindrical
object.
Thick ness—Specifies the diameter of the viewp ort
or rendered spline mesh. Default=1.0. Range=0.0
to 100,000,000.0.
Splines rendered at thickness of 1.0 and 5.0, respec tively
Sides—Sets the number of sides (or facets) for
the spline mesh n the viewport or renderer.
For example, a value of 4 results in a square
cross-section.
Angle—Adjusts the rotational position of the
cross-section in the viewport or renderer. For
example, if the spline mesh has a square cross
section you can use Angle to position a "flat" side
down.
Rectangular—Displays the spline’s mesh shape as
arectangle.
Lengt h—Specifies the size of the cross–section
along the local Y axis.
WidthSpecifies the size of t he cross–sect ion
along the local X axis.
Angle—Adjusts the rotational position of the
cross-section in the viewport or renderer. For
example, if you have a square cross-sect ion you
can use Angle to position a "flat" side down.
Aspect—Sets the aspec t ratio for rectangu lar
cross-sections. The Lock check b ox lets you lo ck
the aspect ratio. When L ock is turned on, Width is
locked to Length that results in a constant ratio of
Width to Length.
