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
______________________
set cut_paste_input [stack 0]
version 8.0 v6
Read {
inputs 0
cacheLocal always
format "2048 1152 0 0 2048 1152 1 RR2_2K"
first 1000
last 1024
origfirst 1000
origlast 1024
origset true
name Read1
selected true
xpos 440
ypos -96
}
Dot {
name Dot1
selected true
xpos 386
ypos -27
}
NoOp {
name NoOp_TCL_metaData
label "\[metadata input/filename]"
selected true
xpos 352
ypos 68
}
NoOp {
name NoOp_PY_metadata
label "\[python nuke.thisNode().metadata(\"input/filename\")]"
selected true
xpos 352
ypos 119
}
Text {
message "TCL expression:\n\[metadata input/filename]"
font C:/Windows/Fonts/arial.ttf
size 28.5
xjustify center
yjustify center
box {2044 483 -4 773}

selected true
xpos 352
ypos 202
}
Text {

}

}

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
