Quote - Mizrael.. I just noticed.. on your pic only the pants themselves are casting shadow, not James...

Do you know why? It looks odd O_o

(and I'm not complaining over a test render, I just want to know what causes it)

Um, he casts a shadow where the ground plane is present. I originally had the file set up so his shadow cut off at the edge of the ground before it drops off to the water below. That last image the ground plane extended a bit to far out past the backgrounds image of the ground and not far enough to catch all of his shadow. Simple enough to fix but as you said, these are just test renders to show the clothing progress, not my artistic skills or lack there of. LOL! Good catch though and good question, but it's just misplacement of the shadow catching ground plane dear.
