Spline Wrap Basic Coord. ObjectObject Properties
Place the spline (or spline primitive) along which an object should be deformed. The quality of the spline’s interpolation will have an effect on the quality of the deformations. The object to be deformed should also contain enough subdivisions to allow it to be deformed.

| The pen is pointing in the X-direction of the world coordinate system. Set Axis to either +X or -X if the pen should be arranged along the length of the spline. |
Imagine the axis as a direction in the world coordinate system that runs along the length of the Spline Wrap, passes through the original undeformed object, and transfers object vertices onto that object. If you use an oblong-shaped object that would normally run along the length of the spline with its longitudinal axis, the object will point in a direction of the world coordinate system and Axis should be set accordingly.
Use this slider to adjust the overall strength of the deformation. In most cases, the slider can stay at 100%.
Use this slider to move the deformed object along the spline. Values of less than 0% and greater than 100% can also be defined - this can lead to interesting effects, especially when End Mode is set to Extend.
From [-10000000..10000000%]
To [-10000000..10000000%]
Use these sliders to define over which stretch of spline the deformations should take place. For example, if From is set to 0% and To to 100%, the deformed object will be stretched along the entire length of the spline.

| Modes from top to bottom: Fit Spline; Keep Length; Spline Wrap turned off. |
Depending on which option Mode has been set to, 0% (From) and 100% (To) will have the following results:
The object to be deformed will be stretched to fit along the length of the spline.
The object to be deformed will maintain its length with regard to the above-mentioned axis.
 |
| Top to bottom: Clamp mode; Extend mode. |
The End Mode options have the following effect when an object is moved along the length of a spline via the Offset slider:
The object will end at the ends of the spline.
The object will extend beyond the ends of the spline in accordance with the direction of the respective end, and will not be deformed further.
Size
 |
| Size and Scale examples. |
Use these function graphs to define the apportionment of size along the length of the deformed object. Scaling occurs on a plane vertical to the spline tangent. The graph’s X-axis reflects the length of the deformed object, i.e. if the object is moved along the spline via Offset, its scaling will remain constant (in contrast to the Spline Size graph).
Size Strength [-10000000..10000000%]
Use this slider to adjust the strength of the spline scaling.
Use this function graph to define the change in scaling of the deformed object over the length of the spline, i.e. if the object moves along the length of the spline via an Offset variation, the objects scaling will be modified dynamically.
Spline Size Strength [-10000000..10000000%]
Use this setting to adjust the spline size strength.
Rotation
Banking [-10000000..10000000°]
Use this setting to rotate (bank) the deformed object uniformly around its long axis.
Use this graph to twist the object into itself along its length. The strength of this twisting is defined by the following setting, Rotation Strength.
Rotation Strength [-10000000..10000000%]
Use this slider to define the strength of the Rotation effect described above.
Use this graph to twist a given object along its length, i.e. if the object is moved along the length of the spline using Offset, the degree of twisting will vary according to position.
Spline Rotation Strength [-10000000..10000000%]
Use this slider to adjust the strength of the Spline Rotation described above.
Unwanted effects can occur with regard to shared bounding boxes when opening a scene on a different system or when rendering using NET (especially when several objects are deformed in the course of a given animation).
A shared bounding box is a virtual cube that encompasses and defines all objects deformed by the Spline Wrap.
When these objects are animated the bounding box will change accordingly and results in a change of position of the deformed objects. If this option is active, a fixed bounding box will be used that will keep the deformed objects in place.

| Spline Wrap is used to deform a Text Object. The splines are generated with the help of a Tracer Object. The text at left looks far less dynamic than the text at right, to which Up Vector was applied. |
Use this setting to make the object deformation more dynamic. Enter 1 in one of the available fields.
