Nuke merge mat. If you understand how alpha works masking should be straight forward. Using merge material in nuke for camera mapping cg earlyworm with a post showing how to camera map multiple projections onto one object in nuke using the mergemat node which allowys you to composite all your projecte3d nodes togehter before applying them to an object. On this page the wiener filter is used as the restoration filter for details you can refer to the tutorial out of focus deblur filter in order to synthesize the wiener filter for a motion blur case it needs to specify the signal to noise ratio snr len and theta of the psf.
