Yeah that's the whole point of it. I did notice however that it was behaving a little unpredictably with Nulls.
I think it has to do with the parameters of the control nodes referencing the top level parameters of the null node. If I delete the reference it seems to multi edit fine.
But yeah, this has definitely saved me whenever I have to multi edit a bunch of nodes. Travelling into them one by one drives you nuts! Here's a little test, if I select this bunch of nodes and run it, then choose ‘Control’.
You can see in the parameter pane there are a bunch of nodes selected.
Oh, I realised I should have cleared the selection, I added a line to the script in the last post.
See how ya go!
