I found a strange effect with shadows in my Poser installation. When I render a scene with a huge distant background plane (to avoid casting shadows onto the plane itself) I realize that all shadows are nearly invisible. when I render the same scene without background plane, shadows are OK. so I started to render 2 times, one with background, but without shadows, and a second time without background, but clearly visible shadows. late I blend both pics together to get the final result. Quite a couple of my latests pics are done this way. maybe I am too dull ...?
