**Vectors** | V | Set of vectors to tween between | Vector |

**Factor** | F | Tween factor (0.0 = Vector at V, 1.0 = Vector at V +1) | Number |

**Weighted** | W | If True, tween distribution is weighted by the input vector set and the tween path curvature | Boolean |

**Loopback** | L | If True, allow the tween path to continue from the end back to the start as a closed loop | Boolean |

**Degree** | D | Curvature degree of the tween path, degree should be a positive odd number | Integer |

**Interpolation Type** | I | Determines how the tween path is interpolated
0 = Linear
1 = Chord
2 = Square Root
3 = Uniform | Integer |
