Thanks Colin. Support says that the bug number you provided will be
fixed in next release, so we will wait and see if my issues are related
to the same bug. =)
Cheers

Regarding horizontal lines in the output: a while ago I raised this with
the foundry and they were able to replicate it.
Bug #14599 if that's any help.

Hey Jud
Cool. I will search some more for it. I was knee deep in shit/comp
when it hit me so I just had to get the shots out the door. =)
The Foundry can't replicate it so it seems like it's somewhat
computer dependent. I will try to remember to post the verdict from
support once we've gotten to the bottom to it. =)
Thanks again and have a nice weekend

I vaguely recall this coming down to some sort of internal math
issue
with compositing/feathering or something like that. A quick google
before hitting bed (long, long hours on a project under
deadline) didn't
turn up anything, but it took me considerable internet searching the
first time around. I'm nearly 100% certain it was how the math was
computed though. Maybe that will ring some bells to someone who can
remember the exact situation.
Sorry I couldn't be of more help... I'll be sure to post if I find
anything.

Seems like it didn't solve everything. Halve black similar
glitches
now, not by far as many though and I can just rerender those
frames. I
assume that would be caused by Scree Despot Black...

Hi again
I found what caused the issues I had. I have sent it in
to the support
with a screen recording and script. If any one want to
take a look in
the hunt of issues in their own script this is what I
sent in:
http://temp.irry.com/neo/__mekaniken/thefoundry/Keylight___Fubar_RandomNoise.hcf.v1.rar
<http://temp.irry.com/neo/mekaniken/thefoundry/Keylight_Fubar_RandomNoise.hcf.v1.rar>
The workaround for the issues I had is:
For the horisontal randon gray solid line: Raise screen
softness to anything above 0.
For the random cross pattern horizontal lines:
Raise Screen Despot White to 1 or more
Cheers

Morning peeps
I have something here in NukeX 6.3v6 that might be
related to the same
bug. One would have hoped that it would have been
fixed by now. =( I
can
reproduce the gray line described here but my main
issue is horizontal
lines of crosses, looks like this:
http://piclair.com/data/llr8m.__jpg
<http://piclair.com/data/llr8m.jpg>
HAve anyone seen something similar?
Solution/workaround? It's totally
random and appears on different frames and different
locations when
re-rendering and seems to be computer dependent too.
No matter what I change in the keylight node it
disappear on the
frame I
currently view but it randomly appears on other
frames...
Cheers and thanks

I have also seen this happen with keylight, it
seems very random,
and is
sometimes fixed by cropping the inputs in some
way...

Hey Kurt
Thanks for letting us know. Sounds to me like it
may be a tiling
issue. Pending the support guys getting back to
you, as a test, do
you find it happens if you use a 500x500 constant?
Nuke splits up frames over a certain size into
multiple tiles to
feed to OFX plug-ins, to reduce memory usage and
speed things up vs
having large image buffers hanging around. If
parts of the OFX
wrapped algorithm are attempting to access parts
of the image
outside of the tile, without requesting it
properly (such as I'm
guess the softness is doing) then you'll see
this sort of thing were
black is getting brought in along the edge of
such tiles. If other
people are getting these kind of artefacts, and
they're not related
to the softness param, see if you can locate
which knob it is which
is causing their introduction, and let the
support chaps know.
Guessing you're probably combining the keylight
matte with a bunch
of other mattes to pull your key before merging,
so as a workaround,
soften the matte as a post process to Keylight
and you should be
good to go.
Cheers

I had just the image and then keylight. To
eliminate some weird
problem with the footage I just connected a
black constant to the
keylight node to eliminate the footage as
problem. The result was
a white alpha - except for the lines. Seems
like another bug I've
found. I sent it to the Foundry to see what
they say.
Here is the keylight in question. When I
take screen softening to

I know you said your example image was
on a straight Constant
node so probably this is a moot
question. But it sure looks like
a bounding box type of issue.
