Method
This node extrudes n-gon shapes along a spline. The spline used to generate the shape must be connected via the Spline Sources input.
Attributes
| Name | Description |
|---|---|
| Visible | Control whether the node is visible or not to the scene. |
| Seen By Rays | Enable the mesh to be seen by the raytracer. |
| Radius | The radius of the shape to be extruded along the spline. |
| Num Radial Segments | How many sides the extruded shape will have. |
| Num Spline Segments | How many sections the extruded shape is broken up into when following the spline. |
| Use Spline Colours | use the colours from the input sspline to |
| Max Visible Age | The maximum length the extruded geometry can get to as a function of age. Only functions with a Node Trail input. |
| Fade Front Duration | How long the front edge fades for as a percentage of the whole spline. |
| Fade Back Duration | How long the back edge fades for as a percentage of the whole spline. |
| Fade Alpha | Fade the alpha values of the generates spline along its length using Fade Front and Back Duration. Requires an alpha supporting blend mode. |
| Fade Scale | Scale the radial size of the spline using the Fade Front and Back Duration. |
| Draw Triangles | Toggle whether the mesh faces are drawn. |
Lines
| Name | Description |
|---|---|
| Lines Visible | Control whether the node is visible or not to the scene. |
| Lines Alpha | Control the alpha value of the lines. |
| Colour | Control the colour value of the lines. |
| Use Vertex Colours | Colour lines based on the vertex colours of the geometry. |
| Blend Mode | Control how the lines blend with the rest of the scene. |
| Thick Lines | Use lines with thickness relative to their distance to the camera. |
| Hide Back Face Lines | Hides the lines around back faces of geometry. |
| Lock Width | Lock the line width to be consistent regardless of distance from the camera. Only functions with Thick Lines enabled. |
| Thick Line Width | Control the thickness of all the lines. Only functions with Thick Lines enabled. |
| Show Silhouette Lines | Draws lines along the edges of the object relative to the camera. |
| Show Normal Difference Lines | Draw a line along the edges of the mesh, depending on the angle difference between their mutual faces. |
| Show Unshared Lines | Draw lines along all edges of the shape. |
| Show Other Lines | Show all the lines for each edge of the Mesh. |
| Unshared Lines Weight | Greater control over the alpha of the unshared lines. |
| Silhouette Lines Weight | Greater control over the alpha of the silhouette lines. |
| Normal Difference Lines Weight | Greater control over the alpha of the normal difference lines. |
| Other Lines Weight | Greater control over the alpha of the other lines. |
| Line Normal Difference Angle | Change the threshold angle between two face normals that will generate a line along their common edge. Only functions with Show Normal Lines enabled. |
| Line Normal Fade Sharpness | How much the drawn normal lines will fade away the closer the edge angle is to the Line Normal Difference Angle. |
| Line Depth Bias | Exaggerate the width of the lines based on the distance to the camera. not functional with Lock Width enabled. |
| Line Silhouette Fade Sharpness | How much the drawn silhouette lines will fade away based on the size of the edge angle to the camera. |

Inputs
| Name | Description | Typical Node Input |
|---|---|---|
| Spline Sources | Spline nodes used to draw the extrusion along. | Spline |
| Material | Override the default material with another material. | Materials |
| Transform Modifier | Links all transform properties to the input node. | Null |
| Target Node | Always faces the x-axis towards the inputs anchor point. | Null |
| Local Transform Override | Override the transformation values of the node, relative to its parent. | Null |
Outputs
This node outputs the normal transformation and translation values, but it also outputs geometry which can be Deformed or used as a mesh source by other nodes.
