Thank you. I finally got an alpha animated through Oppacity (I read the manual). Working great. I made a .png sequence and I get a solid black background color and no alpha channel. So I do get geometry with animated transparency (desired) but composed against a solid black background color (where is the alpha?). Do I automatically get no background color when I render floats? (.exr?)
