So im trying to put a wound on a girl in my shots face using the following technique:
Track a camera to the face to stabilize it
Make a rogue model of the face
Read in the geometry, and project 3d with your shot as the image (essentially keeping everything the same, jsut projecting the original image back onto that geometry)
Then use a scanline rendere set to uv to get the UV view of your footage
Then you merge over your wound or whatever it is you are tracking to the face, place it on the UVs, and project it back.
My problem is when im projecting the original image back onto the face model, everything looks okay in 3D view through the projection camera (ie i can see her face placed on the model, not perfectly tracked, but decently, thats not the problem), but when i use a scanline render in UV mode im getting nothing but black in my viewer. Its not outputting the UVs… im not sure where ive gone wrong, but obviosuly i have.
Ive attatched a picture of my nuke script (with the viewer on my scanline render so you can see the blackness) and also a little picture form my 3D view through the projecting camera so you can see that it IS infact projecting onto my model.
Anyone know what the problem could be?
