Ok, so lets try an other way to attack my issue.
Can I in some way, keyframe a path to change each frame to some file non
related to a sequence.
ex : frame 1 the path will be mypath/shellH.exr, frame 2
mypath/displace2.exr, frame 3 mypath/colorA.exr ......
cheers

my whole setup is a bit heavy to copy but the principle is simple :
in my gizmo, some attributes are looking for infos in the metadata,
exemple focal length.
as it is to apply corrections to a shoot, the value may change each
frame.
but all of that wouldn't make a difference if it was keyframs anyway
then i have in my gizmo a file with a path full of variables calling
those attributes
ex: mypath/[value parent.focal].jpg
this work in the gui but the render is using only the latest path
loaded when the render was kicked, so if the focal change on a frame
it does't care and still use the wrong file.
I have been told that it is not possible for nuke to refresh that in
its renders (I hope it is wrong), and I would have to iterate all the
frame and create some temp file like 1 nuke script per frame with the
good values baked in...
but I am not sure how to do it and I keep thinking if it can bake
those file it should be able to render those expressions...
I don't know the forceValidate it didn't seems to work but I may have
try it wrong.
thx

The first thing that comes to mind is forceValidate, but I may be
misunderstanding your issue. Can you send an example of the setup
you're using?

anybody know how to force nuke to re evaluate all the expressions in
the script ?
I can maybe use that in the render option if nobody has an other idea.

Hiya,
I have a couple of expressions :
in a few knobs some expressions looking at the metadata to get some
values, then in a read node an expression in the path to feed those
values as the name of the path.
everything is fine in nuke (even if the refresh is not refreshing
the new file until i look something else and get back to it...
ideas welcome)
but when I render the file is the last path loaded, it doesn't
refresh it at all.
Is there anything I can do to force nuke to re evaluate the
expressions and refresh the file for each frame during the render ?
maybe something to add in the tab Python 'before each frame' ??
cheers
Olivier
