Hi All,

I'm trying to learn how to compose Depth Of Field inside Fusion, and so far I've only had a bit of success.
In max, i rendered out an RPF image with floating RGBA + ZDepth + ZConverage channels.

When I plug that image into the DepthBlur node in Fusion, the DOF effect works - but the aliasing along the edges of some objects suggests that the Z Coverage channel of my RPF is not being used properly (if at all).

Can anyone tell me what I should do to get the Z Coverage channel working so the DOF can look ok?

Thanks. :thumbsup:

Reminds me of this discussion at Pigsfly.com:

Not sure if it's exactly the same issue, but might be helpful.
