Merge Node

The Merge node allows one to complete compositing operations, by default it places image data from A overtop B with an “over” operation.


Never consider RGB as being transparent by default - this is OK for unpremultiplied compositing (After Effects) but is invalid in a premultiplied compositor such as Natron or Nuke.

Users still have the option to ignore the alpha channel. (new from v2.4)
