My first using Shadows and Transparency. It took my a while to figure out that you have to go to the render screen and turn on Shadow button. Next time I will read thru the whole Tutorial before I start working on a picture. LOL… I used the Tuitorial “Mastering Shadows” authored by Olivier Saraja. It is posted here in the Tutorial section (of course). It is very informative and easy to understand, so hats off to the Author, and especially Elysium, for this great site.
