Hey i have had experience in other 3d programs than maya in the past and i can tell you one thing. Just take all the tutorials you can find on that one subject and all other tutorials on how to do materials, and then you should be able to do it yourself. Thats what i used to do, if i wanted to make something i would research plainly on that area until i had enough knowledge to do it. Ok, dont know if that helps but yea.
