Wow! Where has this tool been all my Poser life?!?!? It's incredible! Below is a test render of a project I'm working on, using the shadow catcher.

Granted, it's just a first effort and needs a lot of improvement, but it's far better than anything I've ever done before. And to think that before, I was using Paint Shop Pro to add shadows in postwork. The results were ok, but nothing to shout about (see below, taken from my Renderosity gallery)

Shadow cathcher is the way to go - I'm not gonna pretend to even understand everything going on in the material room when I add the shadow catcher material to my ground plane, Bagginsbill, but.... thank you!!
