So my biggest gripe with Affinity Photo has to be the channels workflow. I use my image editor for texture work for 3D and I have to be able to edit color and alpha channels. I was able to do everything I needed with photoshop but I'm not willing to support subscription models, so I would love to be able to just use affinity and not need anything else. Thanks to this post https://forum.affinity.serif.com/index.php?/topic/4730-split-channels/I was finally able to figure out how to create a layer from a channel. (In photoshop this is done by showing only one channel in the channels panel, selecting everything and hitting copy, then pasting into a new layer) Now I need to know how to paste from a layer into a channel. So that I can combine 3 separate images (or layers) into a single image/layer where each of the previous ones is one of the color channels? (In photoshop I would just click on my layer, select all pixels, copy, chose a layer to paste into, show only the color channel I want to edit and paste) Likewise how can I paste a layer into the alpha channel? (In photoshop I could chose a layer, select all, copy, chose a layer, go into the channels panel select the alpha channel and paste)
