Fade Object left to right

I need to fade object left to right. With matarial.color.a i can fade object but the whole part of the object is fading. I want the object is not visible at the beginning then becoming visible toward right

Couldn’t you swap the texture to a gradient texture (off white to transparent, left to right) just before fading then fade the game object with something like.

renderer.material.color.a -= 0.1 * Time.deltaTime * 4;

That might make it look as it’s fading from left to right.
