Material.SetTextureOffset
SetTextureOffset(propertyName: string, offset: Vector2): void;
void SetTextureOffset(string propertyName, Vector2 offset);
def SetTextureOffset(propertyName as string, offset as Vector2) as void
Description

Sets the placement offset of texture propertyName.

Common texture names used by Unity's builtin shaders:
"_MainTex" is the main diffuse texture. This can also be accessed via mainTextureOffset property.
"_BumpMap" is the normal map.
"_Cube" is the reflection cubemap.

See Also: mainTextureOffset property, GetTextureOffset.
	// Scroll main texture based on time

var scrollSpeed : float = 0.5;

function Update () { var offset : float = Time.time * scrollSpeed; renderer.material.SetTextureOffset ("_MainTex", Vector2(offset,0)); }
using UnityEngine;
using System.Collections;

public class Example : MonoBehaviour {
    public float scrollSpeed = 0.5F;
    void Update() {
        float offset = Time.time * scrollSpeed;
        renderer.material.SetTextureOffset("_MainTex", new Vector2(offset, 0));
    }
}

public class Example(MonoBehaviour):

	public scrollSpeed as float = 0.5F

	def Update() as void:
		offset as float = (Time.time * scrollSpeed)
		renderer.material.SetTextureOffset('_MainTex', Vector2(offset, 0))
