Spline

Splines render geometry along a curve. They are typically used to render cable systems. They can be customized to render different types of geometry such as cylindrical cables or mesh chains.

Fields

Field	Description
Visible	Toggles spline visibility.
Cast Shadow	Whether the spline projects a shadow onto other objects.
Receive Shadow	Whether the spline receives shadows projected by other objects.
Graphics Material	Material to apply onto the generated mesh.
Spline Control Points	Control points that define the spline. These can be provided by cable systems or custom scripts.
Technique	Defines the geometry that will be rendered onto the spline. Cylinder: Cylindrical mesh defined by its number of sides, radius and roundness. Strap: Prismatic mesh defined by its radius and roundness. A roundness of 0 renders the strap as a flat surface. Cross: Cross-shaped mesh defined by its radius. Line: Single pixel wide line useful for rendering UI elements. Mesh: Renders a chain of meshes along the spline.
Number of Sides	Defines the number of sides of a cylindrical spline.
Radius	Radius of the rendered spline.
Roundness	Defines the scaling proportions on the different sides of the cable. A value of 1 will produces sides of equal size.
Texture Repeat Length	The number of times the texture is repeated along one unit of the length of the spline.
Texture Repeat Width	The number of times the texture is repeated along the width of the spline.
Interpolation	When active, interpolates the spline between its sections to produce smoother curves.
Subdivision per Section	Number of subdivisions used to enhance the smoothness between each spline section. Used when interpolation is enabled.
Alternate Mesh Rotation	When true, rotates every other mesh along the spline. Useful to render chains with a single link mesh.
Mesh Overlap	Offset that enables overlapping meshes along the spline. Typically used to draw chains.
Mesh Coverage	The size of the mesh on the spline.
Mesh Instances	Number of mesh instances currently being rendered along the spline.
