How to perfect a z-depth channel from .rpf file

[fx-artist]

I'v tried to create z-depth blur by using the 3D Depth of Field operator,but the result is not what i've expected, the blur in the near object seems to be masked out by the z-matte, so the blur just inside of the image (texture color only) not the whole object,and also when see the z-buffer the image seems not anti-aliased. How to solve this ? :cry:

I had the same problem and part of it was solved by using a plugin to do DoF and antialiasing problem was solved by using twice as big image and after compositing scale it down to needed size.
