Hello,
I just bought Affinity Photo and I was kind of surprised how it lacks the option the copy alpha maps in the mask channels (instead of doing selections and then filling them) to be able to avoid crisp edges.
I think it is crucial to have this option as I, as a 3d artist, have ability to render out different kinds of masks (with or without antialiasing)
In case I somehow missed that option please let me know, though I watched some of Affinity tutorials and neither gave me a solution that I was looking forward.
