Fade out a gameobject

I let a gameobject fade out like this:

Code (csharp):

1. for (t = 0.0; t < 1.0; t += Time.deltaTime)
2.             {
3.                 Object.renderer.material.color.a = Mathf.Lerp(1, 0, t)
4.             }

But when it is done, it is still a little bit visible (on my galaxy note). You still can see the contours a little.
I think it has something to do with timing but I'm not sure.
Can anybody tell me how to let it fade out complete?

 

I can suggest workaround - disable mesh renderer, to guarantee visibility of object:

Code (csharp):

1. Object.renderer.enabled = false;

or:

Code (csharp):

1. Object.renderer.enabled = Object.renderer.material.color.a > 0.01F;

 

Here you go

Code (csharp):

1. iTween.FadeTo(gameObject, iTween.Hash("alpha", 0f,  "time", time));

 

The reason of you issue is here "t += Time.deltaTime" - you increnent t variable by deltaTime value.
So if t = 0.95 and deltaTime = 0.5, then next value of t will equals 1.45 and for cycle will not run - last value of t will be 0.95 - and object still a little bit visible.

Alternate way is allow t to be greater then 1:

Code (csharp):

1.    
2. for (t = 0.0; t < 2.0; t += Time.deltaTime)
3. {
4.      Object.renderer.material.color.a = Mathf.Lerp(1, 0, t)
5. }

 

Thank you all for your quick reply.

t greater than 1 was the solution. And I understand why, thanks Patico.
