Changing textures on multiple materials shared by a mesh renderer

Question

Hello. I am working on a project and using JavaScript to change the main textures on materials at the push of a GUI button (renderer.material.mainTexture= whatever). I've been keeping it really simple and so far, things have been moving along perfectly and without any trouble.

However, I just encountered a mesh renderer on a single mesh that is using two separate materials. I apply my texture switcher script and just as I expected, it is only switching the texture on one of the two materials.

I'm attaching the script I am using as well as a screen grab of my inspector. Again, this is working perfectly on everything else except the mesh with 2 materials. Is there a way to change the texture on that second material?

var RaceRedTexture:Texture; var SilverMetallicTexture:Texture; var DarkBlueTexture:Texture; var FrozenWhiteTexture:Texture; var PantherBlackTexture:Texture; var TectonicSilverTexture:Texture; var SchoolbusYellowTexture:Texture; var MidnightSkyTexture:Texture; var BurnishedGlowTexture:Texture; var SolarYellowTexture:Texture; var DeepImpactBlueTexture:Texture;

function AssignColor (chg:int)

{ switch(chg) { case 1:// Race Red gameObject.renderer.material.mainTexture=RaceRedTexture; break;

     case 2:// Silver Metallic
     gameObject.renderer.material.mainTexture=SilverMetallicTexture;
     break;
     
     case 3:// Dark Blue
     gameObject.renderer.material.mainTexture=DarkBlueTexture;
     break;
     
     case 4:// Frozen White
     gameObject.renderer.material.mainTexture=FrozenWhiteTexture;
     break;
     
     case 5:// Panther Black
     gameObject.renderer.material.mainTexture=PantherBlackTexture;
     break;
     
     case 6:// Tectonic Silver
     gameObject.renderer.material.mainTexture=TectonicSilverTexture;
     break;
     
     case 7:// Schoolbus Yella
     gameObject.renderer.material.mainTexture=SchoolbusYellowTexture;
     break;
     
     case 8:// Midnight Sky
     gameObject.renderer.material.mainTexture=MidnightSkyTexture;
     break;
     
     case 9:// Burnished Glow
     gameObject.renderer.material.mainTexture=BurnishedGlowTexture;
     break;
     
     case 10:// Solar Yellow
     gameObject.renderer.material.mainTexture=SolarYellowTexture;
     break;
     
     case 11:// Deep Impact Blue
     gameObject.renderer.material.mainTexture=DeepImpactBlueTexture;
     break;
 }

I answered my own question. It took some digging to find but it was super simple. Multiple materials on a mesh are handled in Unity as an array. Here's the solution for anyone who needs it: (I'm just posting a small chunk of my code.)

function AssignColor (chg:int)

{

 switch(chg)
 {
     case 1:// Race Red
     gameObject.renderer.materials[0].mainTexture=RaceRedTexture1;
     gameObject.renderer.materials[1].mainTexture=RaceRedTexture2;
             break;
     }

}

Anyone know how to do this for GetComponent().material? I have two materials in my renderer. How do I specify the other one when all it allows me to do is choose the first instantiated??

I can't find an answer. I usually figure it out while I post a problem so I'll update here if I figure it out.

EDIT: Okay it was GetComponent().materials to be able to choose which material. So GetComponent().materials[1] will choose my second element (as in second material), [0] will choose the first element (first material).
