Trying to make a soft edged black frame.
This must be so simple but it's eluding me. Can someone please point me in the right direction, in terms of how best to achieve this?
Presently I have a black rectangle the size of my artboard. There is a slightly smaller white rectangle on top, feathered. I thought maybe I could combine these to make the white area transparrent and export with transparrency to use it as a soft edged mask in a media server.
I'm fine with exporting, but I'm struggling to combine the black and the white shape as one, to make the white area punch out. I have been trying to use a knockout group but I think I misunderstood how this worked.
