Why don't you just change the name of the node?  I.e, 'node_2'.. that's the
standard way of doing it.  Otherwise, the answer is... possibly, but it's
going to be extremely difficult, and rather unreliable, I would think.

Subject: [Nuke-dev] Differ plugin loading from adding

Hi all!

I have a plugin, and I have a number of saved projects, using this plugin. I
want add new knob "Version" to the plugin with value 2 by default, and value
1 for loaded projects (that saved with previous version of this plugin,
without the knob). Indeed I need to differ loading plugin from creating one.
Is there any way to do this?

Thanks.
-Georgy
