Change the layer images

Hi guys,

I’m new with Natron and I’m trying to animate a letter image which start with the envelope closed and this envelope opens in the the letter comes out of the envelope. I’m almost done, but when the letter comes out I have this problem like in the image attachment. I would like to know how I can put this part of envelope above in behind when letter starts comes out.

Check some tutorials on node based composing or dig through this forum!

You should use more merge nodes and create some kind of pipeline. Usually one merge node merges a foreground (A) over a background (B) then it goes to the next…

If you ask for help here in the forum, it would be nice to get a response to the answers, so other users searching for the same can read through to thread too.
Otherwise its not very motivating to help you guys.
