Render Output with Alpha channel, for example .png file with alpha channel

Hello,

In some cases skymask is not suitable for a perfect results, so sometimes is not possible to use D5render and we need to go for another softwares.

It would be a great advance if D5 were capable of output renders with alpha channel, sky mask is not enought to work properly in postproduction stage so I think it is really necessary to be able to render for example in a .png format with alpha channel.
I considert it’s a basic feature please.

Exactly like the picture attached, open it in photoshop and you already have the native png transparency from the alpha channel.


Thanks.
