Strange smearing on texture with unity 4.3.4

[Rick74]

So I’m having a weird issue using a scrolling texture script on a sprite in 4.3.4. The sprite was an export from max, but that shouldn’t matter. The script I’m using, I found online which scrolls the verts on the sprite.

This works fine in Unity 4.2.1f, but once I upgrade I get this smearing effect when it’s suppose to loop.

I’ve tried various shaders to no avail. I’m not understanding what could be causing this?

here’s the script it’s using…

#pragma strict

//scroll main texture based on time
 
var scrollSpeed: 		float = .5;
var offset: 			float;
var rotate: 			float;
 
function Update ()
{
    offset+= (Time.deltaTime*scrollSpeed)/10.0;
    //scrolls right to left
    //renderer.material.SetTextureOffset ("_MainTex", Vector2(offset,0));
    //scrolls bottom to top
    renderer.material.SetTextureOffset ("_MainTex", Vector2(0, offset));
}

Sorry, I just researched and found the answer.

Even though my textures wrap mode was set to repeat, I guess it bugged out. I had to select clamp, then changed it back to repeat. Works fine now.
