Using P6, I want to render a character over a static background, so I want it to cast a shadow on the background to blend the two together. I can obviously get the shadow to cast onto the ground plane, but the plane itself is still somewhat visible (it's at roughly a 30-40% opacity). Any tips or suggestions?

Have you just done an Import --> Background image? What you may want to experiment with is loading the one sided square prop and applying the background image to it, then scaling it up to the size needed. Then I'd say texture the ground plane to blend into the background image, or turn off the ground plane and see how things look from there. Someone will hopefully come along with a better answer, but that would be my first idea to try.

Thanks for the reply Realmling. Yeah I Import --> Background image before anything else. It's odd because it seems to happen when my Shadows are set to anything lower than 1, but at 1 it's fine. An alternative solution has been to just lower the Intensity of that light, then set a similar light on or next to it with shadows turned off to retain the intensity I want. This problem might just carry with the pz3 file I always load, which is where my main character is saved to (I don't konw what I just don't save my characters as Figures). Anyway, it could be a strange bug, or perhaps I accidentally changed a setting without knowing it. No big deal... yet.
