merging multiple camera projections

[judderman]

Hi All,

I\'m running in to problems understanding the workflow for merging multiple camera projections on to 3D cards, where the cards are overlapping. At the moment, I have say, 3 different cards piped in to the same scene with some rotopaint work done on them to remove elements.

I have used masks with soft edges to blend the projections on to the original footage (which has been 3d tracked). If I want to keep those cards where they are but not have the chatter i\'m getting where some of them are directly in the same 3d space, should I be merging one over the other? The reason I didn\'t want to do this is I would see my script becoming large and a bit cumbersome. It made more sense to me to pipe everything in to one scene and try and figure out how to specify an order to which the cards are rendered from top to bottom.

I\'m not sure if this makes sense - it\'s really a layering thing I\'m trying to figure out, specific to 3d cards and projections.

Can anyone help point me in the right direction? Here\'s a screenie of my script with some labels. (Ignore the missing footage sequences, the drive the project referenced these is turned off!)

Hi judderman \"Mergemat\" can do this. Insert a \"Mergemat\" node and connect all the project3D nodes out into Mergemat. Add a card node and connect it with mergemat node.....
