In Affinity Photo (PC) I have a Parent pixel layer with nine adjustment layers nested below.
I now wish to replace the contents of the Parent layer only with a new image I brought in.
I can't seem to accomplish this, as pasting creates a new layer. I also tried merging (visible) the Parent layer and the new image layer without success.
So how can you update (replace) a Parent layer with a new image, while keeping the child layers?
