I just wanted you all to know that if you have you object on a solid BG, you can go the the Effects & Presets window and choose Color key. This will give you a color picker or eye dropper. Take that and select the BG color, it will be taken away, you may not see that it is if you used Black. You will see it when you transfer it over to the scene you are trying to use it in. There is an edge thin and an edge feather that you may need to adjust, but this is a fast way to get it done. 🙂 I hope this helps you out. It took me lots of searching before I found what i ws looking for. I had forgotten what it was called, so I looked it up online and could not find it, so I thought I would share.
