The online lessons covered painting in Maya as well. Here's a taste of the variety of 2-D brushed available. Below is another example of 3-D painting and how things can animate themselves.
Next they went over something my book didn't which is directly painting on three dimensional objects. So I colored the dino they gave me. They also showed how to paint three dimensional texture onto it as well which is where the scales come from.
This is where I'll stop with Maya's online lessons. They have more but they deal with more advanced stuff like fur, hair and water. They're still very doable since they're introductory but I figure I won't use that knowledge anytime soon. Maybe I'll go back if I get bored with my new book.
