How to make a trail "scroll" or "tile"?

Hello,
First, I'm not sure this thread is in the right section...
On to it, I have a trail for my ship, but as of now it's just attached and it streches as the ship moves.
I would like to make it scroll backwards (like the colors do), is there a way to do this?
Thanks.

 

Hello, I've figured it out as another user told me. My solution was in this: https://docs.unity3d.com/ScriptReference/Material.SetTextureOffset.html
