I didn't understand your terminology at first, but I think we're talking about the "Distort by normal" feature in the Power Fractal Shader. If so, this effect emerges when you apply the shader to a surface with some relief that causes the surface normal to change, as it does on any typical terrain. Passing the shader through other function nodes should be OK. If you want to preview the shader, bear in mind that the shader responds to the context in which it's being previewed. If you preview the shader directly without any terrain input, it would just preview a plane so you won't see the effect. But if you plug it into a shader that is applied to your planetary surface, you can preview it as long as the preview has all your terrain displacements upstream.
