Material.mainTextureScale

Description

The scale 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.GetTextureScale or Material.SetTextureScale with the property name of the main texture as a parameter.

Additional resources: SetTextureScale, GetTextureScale, ShaderLab: Properties, ShaderPropertyFlags.MainTexture.

    void Update()
    {
        // Animates main texture scale in a funky way!
        float scaleX = Mathf.Cos(Time.time) * 0.5f + 1;
        float scaleY = Mathf.Sin(Time.time) * 0.5f + 1;
        rend.material.mainTextureScale = new Vector2(scaleX, scaleY);
    }
