Bryan, OK thanks for clearing that up. 🙂 But still I’m a bit confused 🙂 Sorry. 🙂 Did you try importing an image (a png file – also works with a sequence of png’s)? They show up as a reference layer. And you can turn it on/off with the eye-icon.
You probably did this and now you are asking if there’s a way to have this image separate – not as a layer in the x-sheet? There’s not a feature that does that now. But of course we could make that. But then I need to understand, why you don’t think it works having it as a layer in the x-sheet? Just want to learn, so I can make Animation Paper as good as possible and still keep it simple and uncluttered.
