as in the picture shown, why cannot I find an alpha channel in the OpenEXR Multichannel file Output section?
everything else is there (it has been rendered and saved!). In the Picture you can see a trick to create an alpha channel with a color ramp. That is not precise, is it premultiplied or what ? What am I missing or is the alpha channel hidden within the “combined” channel? (and why is it not a separate channel in the image node?).
Please Help me out!
