hello everybody. after one week with carrara i love it. just started to work with bones, so much fun. anyway, the mask thing, well i'm using vegas video 4.0. my solution is to make the background and plane total white. then i render the scene with my object (whatever it may be) then i render the same scene but i change the texture of the object i am rendering to pure black. in vegas i invert the movie (the masking part) and waa la, my instant mask, with shadow and all
