Alpha Transparency and Save As Image PNG not working

[jujubee]

I have a setup with a backdrop which I've made alpha in Max.
If I export this scene to Vantage then do a quick Save as Image out to .PNG, it loses it's backdrop/alpha channel.
However, If I save it out to .EXR it keeps the alpha channel/works but generates a much larger file.

I notice that if I try a "High Quality" rendering it gives the option to save out the Alpha for PNG in the popup dialog.
Is there a way to get this to simply save out the Alpha channel under the file menu instead?

Thanks.

Hi jujubee,

There is an option Toggle in Edit>Preferences>Files called Opacity(alpha) in quick saved PNG. Enable this and it should save the png with alpha. Please tell us if it works for you.

Best regards,
Alexander
