I really would appreciate a little help with two Nuke questions.
I have very recently started to use Nuke as part of my animation course. One of my lecturers was talking about render passes in Maya today and insists that AO passes need to be plus rather than multiply in Nuke.
I have always been under the impression that AO is used as a muliply operation. What is the best way to use AO in Nuke? Also, is there a particular order that render passes need to be placed in the node tree? I have my first Nuke assignment and I have been given a number of render passes to composite together over a tracked piece of footage.
Any advice would be superb.
