Removing Seam from Polar Coordinates

Hi Everybody,

 

I'm using fractal noise and polar coordinates to try and get a tempest cloud-like look. I'm having some success, but...in using polar coordinates I have this seam repeat at the 0/top part. I imagine this is a known thing, but I can't seem to figure out how to make this effect seamless. 

 

Are there anhy known patches or tricks for this? None of the setting and reversing is working that I've tried.Screenshot 2024-05-02 at 12.11.08 PM.png

Try nesting the current Comp into a new Comp.

Duplicate the nested Comp.

Change the Rotation of the duplicate Comp to 180 degrees.

Apply Radial Wipe to the duplicate Comp and set the Radial Wipe properties as follows:

  • Transition Completion: 75%
  • Start Angle: 0x+224.0
  • Wipe Center: 960, 540 (or center value of the Comp)
  • Wipe:  Clockwise
  • Feather:  150

 

It should look something like this:
