Curve to Tube Node¶
The Curve to Tube node generates a mesh tube along an input curve. It creates cylindrical or custom-profiled geometry that follows the curve shape, with flexible control over radius, resampling, capping, and UV generation. This node is useful for modeling cables, pipes, wires, or other tubular structures.
Inputs¶
- Curve
The input curve to generate the tube along.
- Scale
Distance factor multiplied by the curve’s radius attribute to define the resulting tube radius.
Profile¶
- Profile Mode
Method used to define the profile shape of the tube.
- Round:
Uses a circular profile to define the tube cross-section.
- Custom:
Uses a custom object or geometry as the profile shape.
- Resolution Round
The number of points around the circular profile. Also defines the resolution of the Round cap type.
- Profile Input Custom
Defines how the custom profile is provided.
- Object:
Uses a single object as the custom profile.
- Geometry:
Uses input geometry directly as the profile.
- Object / Geometry Custom
The specific object or geometry to use as the profile when Custom mode is active.
- Shade Smooth
Enables smooth shading for the generated mesh.
Resample¶
Resamples the input curve before generating the mesh. This helps achieve evenly distributed geometry and consistent resolution along the tube.
- Resample Mode
Determines how the curve is resampled.
- Evaluated:
Uses the existing evaluated curve points.
- Auto:
Automatically determines an appropriate sample length based on curve details.
- Count:
Uses a fixed number of sample points.
- Length:
Uses a fixed distance between sample points.
- Scale Auto
Scale factor applied to the automatically derived resample length when using Auto mode.
- Count Count
Number of sample points along the curve when using Count mode.
- Length Length
Distance between sample points when using Length mode.
Caps¶
Fills the open ends of the tube with cap geometry.
- Caps Type
Method used to fill the tube ends.
- Flat:
Uses a single n-gon to cap each end.
- Round:
Uses a half-circle shape for rounded caps.
- Custom:
Uses user-provided geometry or an object as the cap.
- Smooth Flat Round
Smooths the transition between the tube body and the caps instead of creating a sharp edge.
- Caps Input Custom
Defines how custom caps are provided.
- Object:
Uses a single object as the custom cap.
- Geometry:
Uses input geometry as the custom cap.
- Start / End Custom
Specifies the objects or geometry to use for the start and end caps when Custom mode is active.
UV Map¶
- Name
The name of the UV map to create or modify on the output mesh.
- Parameter U/V
Defines how the UVs are generated along the tube.
- Factor:
Uses a normalized 0-1 factor along the curve and profile.
- Length:
Maps UVs based on the real length of the curve and circumference.
- Index:
Uses the point indices along the curve and profile.
- Consider Curve Radius
When enabled, the UV generation takes into account variations in the curve’s radius.
Outputs¶
- Mesh
The generated mesh tube following the input curve, including optional caps and UV mapping.
