Hey Dan, I'm trying to get metadata to show on a standard group properties
pane. So far the only trick I've found that works is to make a ViewMetadata
node and use Pick to link it, but that is not formattable and looks ugly. It
seems like only the label will parse TCL commands like [metadata custom/data].
Any ideas?
Thanks! Den

Hi Den,
in my experience, if the data is non-image, then the metadata route is the best
place to pass data through the pipe. If artists are likely to change or move
the node setup, then your receiver node can simply pop up a warning if it
expects some metadata and doesn't receive it.
Another way of doing things is having a node that looks up-stream for a
particular "data source node" any time the original node's input is changed
(although I don't know if the inputChanged event is fired in Python.) Searching
the DAG upstream is relatively quick, and it only happens when the input is
changed. (Although it won't fire if an upstream node's input is changed. You'd
need to perform separate hash checking to test for that.)
Hope that helps,
Dan.

Hey all, I'm wondering if people have favorite ways of passing data down a
pipe, and the pros and cons. I am thinking of using metadata, though the artist
could strip it by accident. Then there's channels, with similar problems, but
the advantage of holding a lot more data in a matrix. I also thought about
having a separate database stored in root, but then I'd have to parse the
upstream which can get heavy. Could also use variables in custom knobs or
filenames, but that seems easy to get messed up if an artist duplicates a knob
or moves it. I'm sure I'm also missing some other method...
My goal is when the artist creates or moves an in-house Node it auto-populates
with data from upstream.
Thanks!Den
