What is the luminous texture name of the Self-Illumin/Bumped Specular material?

Hello,

I am setting the textures of a prefab when instantiated through scripting. I can set the main texture using SetTexture("_MainTex",texture) and its working but I also want to set the texture that appears in the inspector as Illumin (A). What is the name for that one or where I can find it?

Thank you!

Have a look at the shader code. http://forum.unity3d.com/threads/2085-Builtin-Unity-shaders-source
