'Follow Active Quads" not working? I need to texture the mesh trying to add a UV map to it first. Clicking "Follow active Quads" has no effect whatsoever in the UV/image editor. Using Blender v2.71 and cannot figure out the problem here I tried many times and made new files but nothing is giving a response in the UV editor.
 I did everything exactly as in this tutorial https://www.youtube.com/watch?v=MVh2KG01Qtk

EDIT


Just tried again, similar results. I opened a new file, deleted the cube, added a plane, added a nurbs curve added array modifier and curve modifier to plane, applied modifiers, this time resulting in a white plane after selecting follow active quads:
EDIT

If you are using an array modifier the mesh of your object is sill only one plane that is repeated along a curve. The follow active quads will not work until you apply the modifier: only then your mesh will be a sereis of connected planes.

Once you do that then you can do proper unwrapping.

First select just one face.

Select then all of the faces (press A).

You'll see that the face you had selected first is marked as active (with a dotted pattern)

Then do unwrap (U) Follow Active Quads.
