Would the first step be to start recording the action, and then unlock my white bg color layer, and turn it black? Would that be sufficient to replicate the first step to create the black bg layer visible in the overlay effect? And how do I recreate the next layer? Can actions record layer creation if I copy and paste the layers from the effect psd file into my new file where I am recording the action? I didn't find a way to move the layers over to my tab where the recording is active so that it would be recorded by the action. If I have to create it manually, how do I create the second one, from down?
