I'm still working on the tutorial. I've got most of it written. Now it is just a matter of walking through the steps and getting the screen shots and renders and making sure that it works like I expect it to. (I've already had to make a few corrections to it.) There are going to be tons of images for this tutorial. So I don't think anyone will have problems following along. Given how long it has taken so far, I estimate that it might take another week or two to complete the tutorial. Part of that is because I want to include some animations to illustrate how some of the nodes work. The render time alone will make that a slow process. Anyway, I just want to let people know that I'm still plugging away at it.
