Hi. I'm really going that someone can help me figure this out. I'll try and explain the best I can.
I have a digital painting with fading transparent gradient elements in the upper layers that rely on the background layer for their opacity. I want to take those layers and have them "pick up" or merge with that opacity of the background, but only in the areas where the info of the upper layers overlaps the background. The goal is to give those upper layers with the transparent gradient elements a backing while leaving the negative spaces free so that they can then stand alone as an opaque design on a transparent layer without relying on an overall background. I'm really hoping there's an easier and cleaner way besides just merging the layers with the background and then painstakingly selecting and cutting out all the negative bits. Hopefully, I explained this well enough... Apologies if I made it way more complicated than it has to be, haha
