Full range Color Ramp

[Colacuve (Nomo)]

Hello!

This is a very noob question, but I’m trying to simulate the effect of Start and End mapping on to the pipe that follows the X axis, moving the black across the pipe starting from one end to another. I tried using Color Ramp, but for some reason the start seems arbitrary. I was wondering if I could get some help remapping this?

my guess is your X value does not fit smoothly between 0 and 1, so you’ll need some kind of map range or somesuch before the color ramp.

That will only work without problems with uv map, specially if the curve goes back.
