function GetTexture (propertyName : string) : Texture

Description

Get a named texture.

Many shaders use more than one texture. Use GetTexture to get the propertyName texture.

Common texture names used by Unity's builtin shaders:
"_MainTex" is the main diffuse texture. This can also be accessed via mainTexture property.
"_BumpMap" is the normal map.
"_LightMap" is the lightmap texture.
"_Cube" is the reflection cubemap.

function Start () {
var tex = renderer.material.GetTexture ("_BumpMap");
if (tex)
print ("My bumpmap is " + tex.name);
else
print ("I have no bumpmap!");
}
