Material.mainTextureOffset

Description

The offset of the main texture.

By default, Unity considers a texture with the property name name "_MainTex" to be the main texture. Use the [MainTexture] ShaderLab Properties attribute to make Unity consider a texture with a different property name to be the main texture.

This is the same as calling Material.GetTextureOffset or Material.SetTextureOffset with the property name of the main texture as a parameter.

public class Example : MonoBehaviour
{
    // Scroll the main texture based on time

    float scrollSpeed = 0.5f;
    Renderer rend;

    void Start()
    {
        rend = GetComponent<Renderer> ();
    }

    void Update()
    {
        float offset = Time.time * scrollSpeed;
        rend.material.mainTextureOffset = new Vector2(offset, 0);
    }
}
