Zdepth effects per object

[aaron_johnson]

i have a question for combustion compositing gurus:

i have a scene and a character rendered in seperate diffuse passes. i want to create motion-blur in post on the character only (note: i don't have combusiton yet so i can't test this).

my preferred method of getting Zdepth info would be to use a depth-shader in maya (fake Zdepth, but i've heard it will still work).

now i'm guessing to apply post 3D effects to the character only i have to render a Zdepth pass for the character by itself, with the scenery matted out.... correct...?

not only that, but any other passes like shadow and specular will have to be rendered seperately for the scene and character...?

Note: not a C3 guru but...

Yes render out charachter seperately or you'll have to add a blur to the surroundings as well since in C3 your going to key the Z-depth channel or fake zdepth.

BTW: I was wondering how, and know now that you can in fact use the z-depth data from Maya in C3. Don't need to fake z depth unless speed is an issue.

You have to render out in Hardware rendering your object with z-depth checked to iff format. Pull in your iffs and add a show G buffer operator to it and walla it works.
