P_Project [NKPD]
Author: Franklin Toussaint - http://franklinvfx.com/tools-2/

Camera projection using the render of "World Position" and camera.
The most important advantage of this one is that it's a very light tool (you don't need to import in Nuke a heavy mesh).
So it's fast and easy to use, but still has to have the position pass and the 3D camera.
Tool Details
- P Channel: Select the Position Pass channel
- Project Frame: Select the reference frame (hold the camera who does the projection)
- Hold Image: Frame hold the input image at the same frame as the camera
- Crop: Project or not outside of the format area
- Antialiasing: Reduce the edges aliasing problems
- (Un)Premult: Keep nice shapes on edges
