whenever i make a background for my signature on ps i want to put a render on top of it but when i open the render it comes out on a completely new document so i cant drag it on to my background how can i get it on my background??
You can drag it. It hover over it, hold the mopuse button down and drag it to the background. if that doesnt work, just copy and paste.
Once you have the render cut out Ctrl + Click the layer then hit Ctrl C to copy and go to your sig and hit ctrl v to paste...
what he is saying is when hold ctrl and click on the layer and then hold crtl and while holding it press c than after that click on the layer that you want it on and hold crtl and press v. that is what he is trying to tell you.
