title: Shader Graph, texture not looping
body: <p>I would like to make a shader using shadergraph, but i got a little problem.</p>
  
  <p>I have a texture like this 
  <a href="https://i.stack.imgur.com/FLDzX.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/FLDzX.png" alt="enter image description here"></a></p>
  
  <p>I would like to move over that texture over time to make some sort of laser effect, but it works only at start, cause when the time goes too high, my texture is a become a simple line

  <p>This lane appear even in shadegraph, if i go to much left or right on the offset of the texture, it doesn't loop, it just show the last point infinitely. I would like that when my texture end it loop back to the same texture forever</p>
  
  <p>What do I miss pls ?</p>
