How to create outgrowing stripes/planes from object center? I am trying to create the 'pumpkin creases' like it displays in my poorly created image.
I can't explain it with words but it looks like magnetic fields? It is also the reason I am posting a question because I simply can't find the right words for describing this.
I need it as shader of course.
So the 'texture' from top would look like outgrowing spikes or lines from center.

Not totally sure this is what you expect.

Though, from object &quot;texture coordinates&quot; you can take x and y value so that &quot;arctan2&quot; math node gives you the angle around z axis (between -pi and pi).
Then use this multiplied angle with a sinus (a value between -1 and 1) and plug it as displacement height.
The sphere has some subdivision thanks to subdivision modifier.
Also, the material settings (using Cycles) has a displacement set to &quot;displacement and bump&quot; or &quot;displacement only&quot;.
