Hi guys,
How can I implement solutions like this in Hiero or Nuke Studio?
I'm looking to include a bit of python into the "before render" of a write
node generated by the export process.
If you make a comp node, and then version it up, so that it would be
rendering to a non-existent directory (ie. SHOT010_comp_v02)
If you render this in the timeline, it will *error *because it can't make
that new directory.
Thanks,
Ryan
