Script to quickly change the starting vertex of a shape layer's path. Essential for controlling the animation start point, especially when using Trim Paths.

Features:

• Vertex Rotation:
  • Rotates the order of vertices in a path, changing the start point.
  • Default rotation moves the last vertex to become the first (clockwise shift of the start point).
  • Alt key modifier reverses the rotation, moving the first vertex to the end (counter-clockwise shift).
• Smart Selection:
  • Works on selected shape layers or specific selected path properties.
  • If no path property is selected on a layer, it scans the layer to find path properties.
  • Can process multiple layers or paths simultaneously.
• Keyframe Handling:
  • Updates existing keyframes at the current time.
  • Sets the value directly if no keyframe exists at the current time.
• Workflow Integration:
  • Useful for quickly changing the direction or starting point of Trim Paths animations.
  • Non-destructive operation.
