Hi, I've seen in the Nuke's user's guide one chapter titled "To view a scene over a 2D background image". It says how yo view a 2d output within the 3d view using a "wipe" from within the 3d view with the B channel connected to a 2d node.
This way, if I adjust the opacity, I can see a blend between the 3d wireframe and the 2d backgorund, but it's not very appropiate to work with since all is semitransparent.
I'm confused with the explanation since it shows a screenshot where a background is showed under the 3d wireframe without any transparency adjustent. The wireframe is just over the background like an over operation. How can I accomplish that????
