Special Curves

by sum studio in Modifier Setups

This addon add some curve object to blender. 

8 chains and 3 arrows.

How to use

  • Go to 3D View.
  • Add > Curve > Arrow or Chain.
  • Once you created object from above and select it, properties will appear in 3D View > N Panel > Item > Special Curves.
  • To convert mesh this object, press Convert to Mesh button in panel.


  • Arrow
    • Type: Arrrow types(Round / Rect 1 / Rect 2).
    • Both Tip: Arrow directs both tip or not.
    • Root Scale(when Both Tip is 0): 1 is normal.
    • Curve Resolution: This determine arrow's smoothness.
    • Shade Smooth
    • Auto Smooth Angle(when Shade Smooth is on)
    • Material: Set arrow's material from here.
    • Resolution(when type is Round): Resolution of side of cylinder.
    • Radius(when type is Round): Radius of cylinder.
    • Tip Radius Offset(when type is Round): Difference scale between cylinder radius and tip radius. 1 is same radius.
    • Tip Length(when type is Round or Rect 1):
    • Width/Height(when type is Rect 1 or Rect 2)
    • Tip Width Offset/Tip Height Offset(when type is Rect 1)
    • Tip Width/Tip Height/Tip Thickness(when type is Rect 2)
    • Both Side(when type is Rect2)

  • Chain
    • Type: Chain type(Chain / Round Chain / Circular / Rain / Rectangle / Ball / Circle / Helical / Custom Object)
    • Size(when type isn't Helical): Size of each parts.
    • Rotation: Rotation value from neighboring parts.
    • Start/End: Trim value.
    • Distance(when type isn't Helical): Each parts' distance.
    • Radius(when type isn't Custom Object)
    • Resolution(when type isn't Custom Object)
    • Shade Smooth
    • Auto Smooth Angle(when Shade Smooth is on)
    • Material: Set chain's material from here.
    • Circle Resolution(when type is Round Chain, Circular, Rain or Circle)
    • Width/Height(when type is Round Chain or Rectangle)
    • Ball Subdivisions(when type is Ball)
    • Helical Resolution(when type is Helical): Helical count.
    • Helical Radius(when type is Helical)
    • Fill Caps(when type is Helical): Open or close helical tip.
    • Rotation(when type is Helical): Rotation value along curve.
    • Point Count(when type is Helical): Resolution along curve. This becomes noticeable when changing the rotation
    • Main/Start Point/End Point Object(when type is Custom Object): Object to generate.


    • Ball chain isn't compatible with mutiple curves in one object.
    • Helical chain isn't compatible with use start/end when object has multiple curves.
    • To use UV, you need to convert object to mesh.
    • Set parameter "Distance" in chain to near 0, Blender may slow your PC down.
