I have had this with an earlier version of ZDefocus but not recently.
Checking for NaNs is definitely a good idea.

Any chance there are NANs in the renders?

Hi Nukers,
has anyone of you guys ever got wierd artifacts (infinite color
values) or unstable comps using ZDefocus?
It happened twice now in two different companies with two
different projects and two different version of nuke (NukeX 7.0v6
& NUKEX 7.0v9).
It appears on random frames (in a sequence of 300 frames on 2 or
3) and (I think) only when the focus plane is animated and/or when
I use multiple ZDefocus Nodes in the same comp. Also the comp gets
highly unstable and crashes by only clicking on the ZDefocus node.
In both cases the depth pass was rendered with sitoa to EXR with
the depth info stored in Alpha but I doubt thats part of the issue
since I checked the data and its all normal (no broken pixels or
unusual values).
The thing is, I can get rid of the issue by either disable
"automatic layer spacing" or shuffle the depthpass into another
channel then "depth"? But that only helps for one frame and it
then will certainly appaers on a another random frame. At least I
can somehow fix it but its still pretty annoying. Anyone with
similar experiences or work arounds?
cheers
Falko
