Visibility Switch for objects

I have a character thats animated to pull a sword out of a sheath and then put it back again. I am using two swords and just switching the visibility in Maya. Since Unity doesnt support this part of the animation I need to come up with a script. Any examples of how this can be done? I need to set the visibility for a certain frame range and then turn off for a certain range. Please help! DL out!

 

Code (csharp):

1. //Attach to the game object playing the animation and assign the sword to swordGameObject.
2. var swordGameObject : GameObject;
3.  
4. function switchSwordVisibility (showSword : float) {
5.     swordGameObject.renderer.enabled = showSword ? true : false;
6.  
7. }

Add animation events that call the above function:

Note! You must duplicate the imported animation before you can add event markers to it.

 

Here is a portion of code to display the objects visibility when the correct animation is called

Code (csharp):

1.  
2. void Update () {
3.         if(Mathf.Abs(Input.GetAxis("Vertical")) > 0.1f)
4.         {
5.             animation.CrossFade("run");
6.         swordObject1.renderer.enabled = false;
7.         swordObject2.renderer.enabled = true;
8.         }
9.         else
10.         {
11.         animation.CrossFade("idleSWI");
12.         swordObject1.renderer.enabled = true;
13.         swordObject2.renderer.enabled = false;
14.         }
15.        

It may seem bulky but it works. This is done in C# also.
