I want to do something very simple, but ... i got a light (raytrace on) and a semi-transparent surface with a file textur. BUT: The Raytraced Shadow is just black, the rays do not take up the color of the surface, so that i could have an colored shadow ... What am i doing wrong or how shall i do it? tried now for half a hour and all i got, was an black-and-white projection of my semi-transparent surface, but no colors! Please Help Thanks!
