Splines and Extended Splines 263
You c an animate render parameters, such as the
number of sides, but you cannot animate the
Viewport settings.
You can conv ert the displayed mesh into a mesh
object by applying an Edit Mesh or Edit Poly
modifier or converting to an editable mesh or
editable poly object. If Enable In Viewport is off
when converting, closed shapes will be “filled
in” and open shapes will contain only vertices;
no edges or faces. If Enable In Viewport is on
when converting, the system will use the Viewport
sett ings for this mesh conversion. This gives
maximum flexibility, and will always give the
conversion of the mesh displayed in the viewports.
Enab le I n R ender er —When on, the shape is
rendered as a 3D mesh using the Radial or
Rectangular parameters set for Renderer. In
previous versions of the program, the Renderable
switch performed the same operation.
Enable In Viewpor t—When on, the shape is
displayedintheviewportasa3Dmeshusingthe
Radial or Rectangular parameters set for Renderer.
In previous versions of the program, the Display
Render Mesh performed the same operation.
Use V iewpor t settings—Lets you set different
rendering parameters, and displays the mesh
generated by the Viewport settings. Available only
when Enable in Viewport is turned on.
Genera te M a pping Coords—Tur n t his on to app ly
mapping coordinates. D efault=off.
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.

Real-World M ap Size—Cont rols the scaling
method used for texture mapped materials that
areappliedtotheobject.Thescalingvaluesare
controlled by the Use Real-World Scale settings
found in the applied material’s
Coordinates rollout
(page 2–1434)
. Default=off.
Viewport—Choose this to specify Radial or
Rectangular parameters for the shape as it will
displayintheviewportswhenEnableInViewport
is on.
Render er —Choose this on to specify Radial or
Rectangular parameters for the shape as it will
displaywhenrenderedorviewedintheviewport
when Enable in Viewport is turned on.
Radial—Displays the 3D mesh as a cylindrical
object.
Thickness—Specifies the diameter of the viewport
or rendered spline mesh. Default=1.0. Ra nge=0.0
to 100,000,000.0.
Splines rendered at thick ness of 1.0 and 5.0, respectively
Sides—Sets the number of sides (or facets) for
thesplinemeshntheviewportorrenderer.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 Angl e to position a "flat" side
down.
Rectangular—Displays the spline’s mesh shape
as a rectangle.
