3D prpjection (to UV and back) technique Issue

Hey guys

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?

Calculate Nodes Connected Upstream of an Input

I want to have an expression that will return the number of nodes connected to an input.

Then, toggle the disable based on that number.

i.e. if there are 2 nodes connected to THIS node, enable this node, but, if there is only 1 node connected, then DISABLE.

Anyway to do that?

Thanks so much

Types of texture maps and render passes?

Hi everyone, I am currently doing a research paper into the different types of texture maps and render passes. Besides the standard bump, colour, spec, normal maps and the standard colour, spec, occlusion, ambient, shadow and reflection, could you tell me other types?

I know that the types of passes that are used, are shot based but I would like to know how many of them exists and their purpose.

Thank you!
