Terrific Textures

I'm just writing my manual for the user group, all the subscribers will be getting this manual in a week or two. I just wanted to share some of the textures we will be learning about.

There are two textures here. One for the marble and the other for the glass. The marble texture is really easy to make. It has a shinny surface that reflects the window. I like the way the glass has the suggestion of a background reflection. It's a trick really, the texture is made that way.
