Hi,

I wrote a tutorial on how to fly through a tunnel which deals with this problem, so have a look at that.

Basically, use the Offset effect to move the seam to the middle of your composition. Then you either cover the seam with more fractal noise, or use the CC Simple Wire Removal tool to cover it up.

The term is “tileable”, actually. 🙂

Usually we take the still into Photoshop and uses the offset filter, but Chris’ technique basically does that in AE.

Here’s another trick to create a seamless CC sphere:

(Don’t forget to make your Fractal Noise layer twice as wide as it is high for CC sphere-mapping.)

1. Take the fractal noise layer, create a full-size mask for the layer (double-click on the rectangular mask tool), then shrink the mask in the X-dimension, so it’s about 3/4 as wide as before, but still centered in the comp. Feather the mask in the X-direction so you see a big soft edge on the sides.
2. Apply CC Sphere, set to render “outside” only.
3. Dupe that layer, then apply an expression to the dupe’s Y-rotation value by alt-clicking the stopwatch for that parameter. Leave the resulting expression highlighted.
4. Pickwhip to the first layer’s Y-rotation value for the CC Sphere.
5. Add + 180 to the resulting expression. This will ensure that you have two spheres with a soft seamless edge.

Give it a go …

Steve – this solution looks gorgeous! Thank you!

I made everything step-by-step, the only change I made was I pickwhiped the sphere

Well, that’s sort of what I said, but I’m glad you could see past my clumsy English and figure it out. 🙂

Clumsy???? You

When i’ve done this kind of thing I animated the fractal noise offset and didn’t rotate the sphere. this gives the same effect. the sphere appears to rotate but the cloud pattern changes as the planet rotates instead of staying the same.

also, if it is just clouds that you want photoshop clouds renders paterns that perfectly offset if the size is a multiple of 64 pixels like 1280 x 480. then you can use the pattern for a sphere without any seams.
