I've got a Cycles noise node and would like to give it a flowing effect.

This is kind of what I mean:

enter image description here

I achieved this by sliding the noise distortion back and forth. The problem is that the result looks like it's moving forward, then rewinding; I'd like something that appears to continuously flow.

I can imagine that some clever texture coordinate mapping could do this. Or maybe something else?

  • $\begingroup$ Slide it back and forth works with most ladies but here try to only slide forward (with a driver for example) - it's procedural. That will be a continuous flow. You can also alter the Z mapping axis making a cloud-like effect, where it changes but does not move. You can combine this. $\endgroup$ – Jaroslav Jerryno Novotny Jan 23 '16 at 21:36
  • $\begingroup$ Can't really keep sliding the distortion forward, because eventually it gets too high and looks much different. Changing the z mapping wouldn't work if this was rendered on a sphere, would it? $\endgroup$ – ajwood Jan 23 '16 at 21:39
  • $\begingroup$ For a sphere you need spherical mapping to make the Z be aligned with sphere normals: blender.stackexchange.com/a/45169/7777 and a Z-offsetting will work. If that will work for you I can write it as an answer. $\endgroup$ – Jaroslav Jerryno Novotny Jan 23 '16 at 21:41
  • $\begingroup$ Yeah, I think that'll work as long as you include the sphere mapping bit $\endgroup$ – ajwood Jan 23 '16 at 21:43
