Maybe this is what the OP in the thread below is talking about - I know how to do world-space mapping along the length of an array, what I'm after is 1 UVW tile along the length of the array, a bit like when mapping is used on a sweep (non-WSM). Ultimatelu what I'm after is to run a gradient along the length of each base object sub-spline.

Is it possible? The best I could come up with was the below, but that doesn't seem to work.
