Re: [Nuke-users] OCIO frustrations
Technically environment variables can't change for a running process..
but Python stores them as a mutable os.environ dictionary. However, OCIO
doesn't track changes to Python's os.environ dict, thus the unfortunate
behaviour you are seeing.
The solution to this is using the Context tab on any OCIO node. These
override the environment variables, and can evaluate expressions such as
[getenv ...] or [metadata ...] as Andy mentioned.
We use $JOB/$SEQ/$SHOT in most of our configs, so we do this by default:
ocio_nodes = [OCIODisplay, OCIOColorSpace, OCIOLookTransform]
for nodename in ocio_nodes:
for num, envvar in enumerate((JOB, SEQ, SHOT)):
num += 1
nuke.knobDefault(%s.key%d % (nodename, num),
envvar)
nuke.knobDefault(%s.value%d % (nodename, num),
[getenv %s] % envvar)
..which sets the default for key1=JOB and value=[getenv JOB] on each
of the OCIO nodes, and same for $SEQ and $SHOT
This should be mentioned in the docs, I've made a ticket about updating
the docs in this regard,

Hello all,
Like many of you, I am working inside a pipeline where the client provides a
separate CDL file for each shot. In order to view these properly, the files
must be first in Alexa Log colorspace, and then a CDL is applied, followed by
a 3D LUT file.
One of the things that OCIO seems to mention frequently in the documentation
is its ability to recognize context/environment variables. So, you can look
for ${SEQ}/${SHOT}/grade/${SHOT}.cdl and apply it, in theory, as part of an
OCIO config.
The only problem is, it would appear that OCIO only calculates these
variables ONCE at application startup? I have scripts that run when the
onScriptLoad event handler is triggered that alter these environment
variables based on the script that is opened. However, it would appear that
OCIO is not listening for any changes to the environment variables while Nuke
is running?
Do I have this right? If not, what am I doing wrong?

Re: [Nuke-users] cloud rendering anybody?
Are you sure zyncrender has stopped? I just used them in March, and I didn't get any notifications from them about service stopping. They are great, and super easy to set up.
