Adding distortion to texture based on position
I want to make a material that represent earth view from space, with moving clouds and an independent rotation.
I have this texture from Nasa https://visibleearth.nasa.gov/view.php?id=57747
Using Panner to rotate the clouds is a nice effect, but not natural enough.
Would be possible to add a "random" rotation or some kind of distortion based on the relative position of the globe? (Clouds close to poles move faster).
This answer seems close, but I lose the rotation from Panner. https://answers.unrealengine.com/questions/496738/is-there-a-way-to-add-distortion-to-a-material-for.html

Get a texture coord node and multiply it with noise and use that as the UVs for your cloud texture layer. If you use a vector noise node instead you can pan or rotate the noise in 3 dimensions.

PS: Scale the noise .
