I don´t understand something: If I use the PREVIEW button on Render >Render>Preview, I save the picture as .png and IT COMES with an alpha ready channel.
But if I render a series of images as .png the background comes with NO ALPHA. Ok, I´m very confused now. Why can´t I get an alpha straight out from a sequence .png? Thanks.
