286 Chapter 5: Creating Geometry
Rendering and Interpolation rollouts
These creation parameters appear in these rollouts
for editable splines. For splines to which the
Edit Spline modifier has been applied, creation
parameters are available by selecting the object
type entry (for example, Circle or NGon) at the
bottom of the
modifier stack (page 3–802) .
Rendering rollout
Controls here let you turn on and off the
renderability of t he shape, sp ecify its thickness
in the rendered scene, and apply mapping
coordinates. The spline mesh can be viewed
in the viewports. You can a nimate the render
parameters, such as the number of sides. Viewpor t
settings cannot be animated.
You can also convert the displayed mesh into a
mesh object by applying an Edit Mesh modifier
or converting to an Editable Mesh. The system
w i ll use the Viewport settings for this mesh
conversion if Use Viewport Settings is turned on;
other wise it will use the Renderer settings. This
gives maximum flexibility, and will always give the
conversion of the mesh displayed in the viewports.
The U coordinate wraps once around the thickness
of the spline; the V coordinate is mapped once
along the length of the spline. Tiling is achieved
using t he Tiling parameters in the material itself.
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 V iewpor 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 Viewpor t settings—Lets you set different
rendering parameters, and d isplays the mesh
generated by the View port settings. Available only
when Enable in Viewport is turned on.
Generate Mapping Coords—Tur n this on to apply
mapping coordinates. Default=off.

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—Turn this on to specify Radial or
Rectangular parameters for the shape as it will
display in the viewport when Enable in Viewport
is turned on.
