How to Link Puppet Pin to Null Object in After Effects

Properties to use
Bend (Effect setting)

Copy Code
loopTime = 10; // Loop duration in seconds
amp = 10; // Amplitude of the bend (maximum bend angle)
freq = 3 / loopTime; // Frequency (how many bends per loop time)

// Create a smooth sine wave that oscillates over the loop time
bendAngle = Math.sin(time * Math.PI * 2 * freq) * amp;

bendAngle;

    
/* Adjust value of "LoopTime, amp, freq" according to your requirement */

How to Use?

Open After Effects:

• Launch Adobe After Effects and open or create a new composition.

Select the Layer/Effect:

• Choose the layer or object that you want to apply the Bandio plugin’s bend property to (e.g., a shape, text, or solid).

Apply the Bandio Plugin:

• Apply the Bandio plugin to your selected layer.

Access the Bend Property:

• Find the bend property in the Bandio plugin settings and expand it to reveal its keyframes.

Enable Expressions on the Bend Property:

• Alt-click (Option-click on Mac) the stopwatch next to the bend property to open the expression editor.

Enter the Expression:

• Copy and paste the sine wave expression into the expression editor.

Adjust the Parameters:

• Set the following values:
  • loopTime = 10; (Adjusts the loop duration in seconds).
  • amp = 10; (Controls the intensity of the bend).
  • freq = 3 / loopTime; (Controls the speed of the oscillation).

Preview the Animation:

• Press Spacebar to preview your animation. The bend should oscillate smoothly based on the sine wave.

Done:

• Your bend property is now linked to the sine wave expression, creating a smooth oscillating effect.
