Material.SetTexture

function SetTexture (propertyName : string, texture : Texture) : void

Description

Set a named texture.

Many shaders use more than one texture. Use SetTexture to change 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.

var bumpMap : Texture;
renderer.material.SetTexture("_BumpMap", bumpMap);
