Curve to Tube Modifier

The Curve to Tube modifier 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.

Các Tùy Chọn (Options)

Tỷ Lệ (Scale)

Distance factor multiplied by the curve's radius attribute to define the resulting tube radius.

Mặt Cắt (Profile)

Profile Mode

Method used to define the profile shape of the tube.

Tròn (Round):

Uses a circular profile to define the tube cross-section.

Tùy Chỉnh (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 (Đối Tượng):

Uses a single object as the custom profile.

Hình Học (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.

Tô Bóng Mịn Màng (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.

Tính Toán (Evaluated):

Uses the existing evaluated curve points.

Tự Động (Auto):

Automatically determines an appropriate sample length based on curve details.

Số Lượng (Count):

Uses a fixed number of sample points.

Chiều Dài (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.

Nắp Đậy (Caps)

Fills the open ends of the tube with cap geometry.

Kiểu Nắp Đầu (Caps Type)

Method used to fill the tube ends.

Phẳng Bẹt (Flat):

Uses a single n-gon to cap each end.

Tròn (Round):

Uses a half-circle shape for rounded caps.

Tùy Chỉnh (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 (Đối Tượng):

Uses a single object as the custom cap.

Hình Học (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 (Ánh Xạ UV)

Tên [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.

Hệ Số (Factor):

Uses a normalized 0-1 factor along the curve and profile.

Chiều Dài (Length):

Maps UVs based on the real length of the curve and circumference.

Chỉ Số (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.
