1) This is the Smooth Step Math node. It`s wavelength is set to 0/1/0. The Smoothness parameter is set to 7 or so. It basically determines the smoothness of the transition between clouds and no clouds. Origin is set to 0/-2.5/0. Note: The Origin lets you move the cloud limit. The Origin setting depends on the angle of the camera and some other factors. So you might have to experiment a bit.

  1. Rotation. In this example I used 135 degrees z Rotation. With Vue xStream you might need to use a different angle. Leave all parameters except zRotation untouched.

  2. Combiner node. Combines the Smooth Step node with the Fractal node.

It may require some experimenting with the parameters of the nodes to get the result you want.

Good luck!
