Absolute Nuke Noob question

Hi,

If you guys can't help me, I might throw my computer out the window.

I rendered a background, a foreground and an alpha of the foreground. All I want is to have my foreground on top of the background (of course).

I was thinking of just using a "merge" node to get the foreground (A) the background (B) and the alpha (Mask) but it does not work.

Thank you very much for any help at all!!

use a copy node to copy the alpha into the foreground (if the render is un-premultiplied, you'll have to then put a premult node after that) then it should merge fine.

Thank you so much!

You saved my computer, my window, and probably the car below...
