how to make SetTextureOffset background like this ?

I want this background system using SetTextureOffset. But i cant do it. Please help me.

Goal :

Developers tell how to make it but my poor english prevent me http://www.asteroidbase.com/devlog/bringing-warmth-to-deep-space/

 

I'm not in Unity to test it now, but I would think you could do something like this in a script attached to your background material (which should probably be a child object of the camera like in that example):

Code (CSharp):

1. public Camera theCamera;
2.  
3. void Start() {
4.  rend = GetComponent<Renderer>();
5. }
6.  
7. void Update() {
8.  rend.material.mainTextureOffset = theCamera.transform.position;
9. }

Edit: It seems like using the mainTextureOffset attribute is preferable to SetTextureOffset, so I modified that code to reflect that.
