How to make plane/texture face to the camera view?

[Enfyny]

Ok, let's say i have an image as plane, with adjusted Grass texture on it. I want that texture always facing towards the camera view. How can i do that?

Go to the constraints of your plane (the chain link symbol) and chose e.g. copy rotation and the camera as target.
If you not only want it to face towards the camera but actually stay at the same relative position to the camera you can also just parent the plane to the camera so it moves with it. (select the plane, shift-select the camera, press ctrl-P).
