Igor is right, you can use 'in' for this:
[in MyReadNode {metadata input/filename}]

I am not soooo well versed in TCL (still on my list), but there is the

The /command/ is executed with the /object/ as the "context". This
means that all names are evaluated relative to this object, and
commands that modify "this" node will modify the given one.
If no arguments are given, this returns the name of the current
context. Warning: this name may not give the exact same context if
your nodes do not all have unique names.
Sounds like what you are after.

Hi there,
I am working on a PRECOMP setup for royal render.
So I am creating precomps and inside them I would like to use the
incoming metadata input/filename value to fill empty placeholder
ReadNodes.
These readnodes have the exact same naming as my input metaData
filename exept for one folder name which I like to replace.
But I realized that the way nuke (version8.0v6) handles metaData is
different in evaluation.
here is a small example

the TCL expression:
[metadata input/filename]
gives me for every frame the exact filename in a nodes label and in
for example a TextNodes message knob.
Python metaData:
[python nuke.thisNode().metadata("input/filename")]
the Python version does not update in the NodeGraph like in a label
for example.
But it updates in a textNode
Python metaData from a specific Node:
[python nuke.toNode("Read1").metadata("input/filename")]
does not update in the NodeGraph and seems to be one frame behind
when you skip some frames.
So the TCL expression would be great but I can not specify another
node to read the metadata from. or can I?
Or is there a way to force the python expressions to update?
And I am in a precomp so no beforeEachFrameRender scripts are possible.
Any ideas?
cheers,
Vincent
