uv offset for line Renderer.

For Starters, I am an Artist above all else, I am just learning the JavaScript side of Unity.

I have a line renderer attached (as a component) to a cube and I am trying to offset the UV coordinates via the following code. The script is attached to the Unity Cube:

Code (csharp):

1. // Scroll main texture based on time
2.  
3. var scrollSpeed = 0.1;
4. function Update ()
5. {
6.     var offset = Time.time * scrollSpeed;
7.  
8.     GetComponent(LineRenderer).material.SetTextureOffset ("_MainText", Vector2(offset/10.0, offset));
9. }

Currently; I do not have any compile-time errors and no run-time errors either, but nothing happens.

My end result should be a scrolling line renderer material with a non scrolling cube material.

P.S. This script has been modified from the Unity Sewer-demo Scene.

I appreciate all help/tips in advance.

The property name for the main texture is usually _MainTex, not _MainText. If there isn't a property called _MainText, that would explain why your code compiles but still doesn't work.

 

ah, crap... in all of my editing of the script, I must have messed that up. Thanks Andee, that did it.

 

Texture offset is not the same thing as UV offset, which normally you need a reference to a Mesh instance to be able to alter. The difference may seem slight, but it's rather significant. I've heard that when you dynamically alter the texture offset of a material that is being used by more than one object, a copy of that material is made, which increases the number of materials used in the scene, thus the draw calls, and thus reduces performance. Editing the UVs of a mesh instance, however, does not copy the material, and is the better way to go if you're seeking optimization. So, is there a way do truly edit the UVs through a Mesh instance with LineRenderer?
