Hi John,
The ear sounds painful! I hope you are recuperating well.
Thanks for the workflow. I have got it to work, with SU loading a script automatically (which defines a function to set the current model behavior as I want it) and I call that function in console. It runs slowly compared to the all-Ruby solution - but at least it processes without crash. So I can send lots of files and leave it to run over lunch, or night!
Many thanks again,
Keith
