it works. thank you.

i did a basic script first. it changed the render options interface.
i put the code then into my autorender script and it works great.

after my last post, i realized that i had not tried the poser4 render machine.
it works with the code we had explored.

you (nruddock) have specifically answered two major questions that were stopping me.
in the process, i have also learned more about the syntax.
i don't know how you know this stuff but you seem to have a handle on it.

thanks again.
