Shape Extrusion

Use this module to extrude a Shape along a Path, creating a Volume.

Slots

Input

  • Path - the path to extrude along
  • Shape - the cross shape to extrude

Output

  • Volume - the resulting volume
  • Volume (Hollow) - the resulting hollow volume

Reference

Path

Range

Defines the portion of the Path to extrude. For closed paths From will repeat endless, while it's clamped for open paths.

Resolution

Defines how smooth the extrusion will get. Higher values result in more segments being created.

Optimize

If enabled, the extrusion will segmented by Path's curvation instead of using a fixed distance.

Angle Threhold

Only when optimized

Sets the curvation angle after which new segments are being created

Cross

Range

Defines the portion of the Cross shape to extrude. For closed shapes From will repeat endless, while it's clamped for open shapes.

Resolution

Defines how smooth the extrusion will get. Higher values result in more vertices being created.

Optimize

If enabled, the extrusion will segmented by Shape's curvation instead of using a fixed distance.

Angle Threhold

Only when optimized

Sets the curvation angle after which new vertices are being created

Include CP

If enabled, vertices are guaranteed to be created for all shape's Control Points.

Hard Edges

If enabled, extra vertices are being created at Control Points having Hard Edges enabled in their Generator Options.

This is useful for proper lightmapping of sharp corners, e.g. if extruding rectangles
Materials

If enabled, additional patches of vertices are being created for different Material ID's defined in Control Point's Generator Options.

Once you have defined different Material ID's you can use the Add Material button in the Volume Mesh module to assign additional materials!
Extended UV

Whether the extended UV data from the Meta CG Options should be included.

Shift

This shifts the starting point of the Cross section:

  • None - the start of the Shape is used.
  • By Orientation - the starting point is shifted to the collision point of the Path's orientation with the cross shape
  • Custom - the starting point is shifted by a certain value
ReverseNormal

Reverses the normals of the generated Volume. Does not impact Volume Hollow, if any.

Scale

Parameters from this section are used to scale the extrusion

Mode

Simple mode scales by an arbitrary value, while Advanced mode uses curves.

Reference

Determines how to apply the scale:

  • Self - the scale is applied over the Path range
  • Source - the scale is applied over the total length of the underlying Path
Offset

Advanced scale mode only

Scale is applied starting at an offset

Uniform

If enabled, the same scale is applied to both X and Y axis of the cross Shape vertices

Scale

The (base) value to multiply the cross Shape vertices

Multiplier

Advanced scale mode only

The value from the multiplier curve is multiplicated with the base scale value

Hollow

A shrinked clone of the resulting volume will be created simultaneous with the “outer” volume. The value defines the percentage the “inner” volume will be shrinked.

This is most useful for creating tubes!
ReverseNormal

Reverses the normals of the hollow volume. Does not impact Volume.
