I have two cels I want to to copy but copy merged. There is a “copy merged” menu item but I haven’t figure out how it works. What I want to do it drag a group of cels (in adjacent layers in this case) and copy them fully merged for pasting somewhere else. Is this possible?
Copy Merged will copy anything visible in your selection in the canvas. It does not work based on what cels are selected in the timeline. Its behavior contrasts to the regular Copy in that it does not only copy the active layer, but all visible layers.
For your task, you can use Copy Merged by hiding the layers you do not want to copy, selecting the area you want to copy (ctrl+a for the whole image), and executing Copy Merged.
Wow. That makes total sense now. I guess it was just to obvious.
