Edge of the UV-island cuts off the pattern

Hi

As you can see the pattern (bubbles) is cut off by uv-island and does't move along the surface.

Thanks

PS

Edge of the UV-island cuts off the pattern's black-thick-line
As you can see the thick-line on the pattern is continuous.

Hello Staglaitor. Thanks for showing this interesting piece of art!
Now, do you have also a question or is this just it?

"The cut pattern"
by Staglaitor

Do you want to know why UV borders can cut off pattern? This depends on your UVs and the projection method. 
If I understand this correctly the pattern is in UV-Space and your UVs are most absolutely likely not continuous.

But maybe I'm completely wrong here and I don't get the whole picture

Thanks to your reply

Yes i know that my uv-island not continuous. 
How can i change projection method not to project the pattern on uv-islands but on continuous surface?

Yes, i know that i can use a brush and set projection method to "alignment to camera" but i use crack-generator and how can i change projection method for generator?

As far as I know you should use triplanar projection in that case. But you will get blending artifacts which might or might not be what you want. Maybe a 3d-noise is more suited but not sure if it's possible to apply really seamless pattern that way.

Yes, Tri-planar partly works. Red arrow shows that there is no seam on relatively flat surface but pattern in not continuous on edge (blue arrow)
In addition the projection is quite broken in other places.

That is was triplanar does. 
You want a 3d-pattern. As I said I'm not sure if substance tools are able to do this. 
Maybe someone else knows.

Use one of the 3d noises and process the result to look like bubbles.
