I’m sure seasoned Nuke users will laugh and scoff at this query, but I’m a long time After Effects user and so far, just find Nuke massively annoying.
Basically, I have three separate files
1) A background plate
2) A dinosaur
3) An AO pass of some shadowsIn After effects, my bottom layer would be the BG plate, dinosaur on layer 2 (it’s got an alpha channel), AO pass (also with alpha) on layer three, set to Multiply blending mode – Voila, everything fits together, job done.
In Nuke, I’ve tried god-knows-how-many combinations of merging the files, but I can’t get them to composit.
(AO > multiply > Dinosaur) merge this over (BG Plate) = dinosaur with shading, but shadows don’t affect BG Plate.
So I figured I’d just try and get the shadows on the ground, and I get this result:
It’s supposed to be an alpha channel, why is it just coming out as black.
This is what I’m trying to achieve – Done in After Effects
Sorry if this is a really basic problem, I’m just massively stuck.

Well, its okay everyone is a newbie at some point of his learning curve.
You just have to merge a white constant node after the AO pass..this is to make the not AO included area which is black to make it white ,then it wont affect the black areas anymore.
